Atom Definition and Examples

Atom Definition and Examples An atom is the defining structure of an element, which cannot be broken by any chemical means. A typical atom consists of a nucleus of positively-charged  protons and electrically neutral  neutrons with negatively-charged  electrons orbiting this nucleus. However, an atom can consist of a single proton (i.e., the protium isotope of hydrogen) as a nucleus. The number of protons defines the identity of an atom or its element. Atom Size, Mass, and Charge The size of an atom depends on how many protons and neutrons it has, as well as whether or not it has electrons. A typical atom size is around 100 picometers or about one ten-billionth of a meter. Most of the volume is empty space, with regions where electrons may be found. Small atoms tend to be spherically symmetrical, but this is not always true of larger atoms. Contrary to most diagrams of atoms, electrons do not always orbit the nucleus in circles. Atoms can range in mass from 1.67 x 10-27 kg (for hydrogen) to 4.52 x 10-25 kg for superheavy radioactive nuclei. The mass is almost entirely due to protons and neutrons, as electrons contribute negligible mass to an atom. An atom that has an equal number of protons and electron has no net electrical charge. An imbalance in the numbers of protons and electrons forms an atomic ion. So, atoms may be neutral, positive, or negative. Discovery The concept that matter might be made of small units has been around since ancient Greece and India. In fact, the word atom was coined in Ancient Greece. However, the existence of atoms was not proven until John Daltons experiments in the early 1800s. In the 20th century, it became possible to see individual atoms using scanning tunneling microscopy. While its believed electrons formed in the very early stages of the Big Bang formation of the universe, atomic nuclei did not form until perhaps 3 minutes after the explosion. At present, the most common type of atom in the universe is hydrogen, although over time, increasing amounts of helium and oxygen will exist, likely overtaking hydrogen in abundance. Antimatter and Exotic Atoms Most of the matter encountered in the universe is made from atoms with positive protons, neutral neutrons, and negative electrons. However, there exists an antimatter particle for electrons and protons with opposite electrical charges. Positrons are positive electrons, while antiprotons are negative protons. Theoretically, antimatter atoms might exist or be made. The antimatter equivalent to a hydrogen atom (antihydrogen) was produced at CERN in Geneva in 1996. If a regular atom and an anti-atom were to encounter each other, they would annihilate each other, while releasing considerable energy. Exotic atoms are also possible, in which a proton, neutron, or electron is replaced by another particle. For example, an electron could be replaced with a muon to form a muoinic atom. These types of atoms have not been observed in nature, yet may be produced in a laboratory. Atom Examples hydrogencarbon-14zinccesiumtritiumCl- (a substance can be an atom and an isotope or ion at the same time) Examples of substances that are not atoms include water (H2O), table salt (NaCl), and ozone (O3). Basically, any material with a composition that includes more than one element symbol or that has a subscript following an element symbol is a molecule or compound and not an atom.

Integrated Spatial Fire and Forest Management Planning Article

Integrated Spatial Fire and Forest Management Planning - Article Example The article puts forward the notion that fire science should reapply many of these metrics so that human activities, the impact of access roads, and other factors are counted alongside the information that has traditionally been accounted for with regards to fire loss estimates as a means of more realistically relating key information to the concerned parties. An alternative view of this particular debate is with regards to the fact that many individuals within the fire service community and forcefully management communities are of the opinion that human impacts upon natural environments cannot be categorically stated or counted in a verifiable manner due to the fact that many of these impacts are created long before forcefully management and/or subsequent forest fires actually take place within the region. Although it is true that certain human impacts to forest management and forest fires as a whole can take place long after the region has been designated as a forestry management a rea or even experienced a forest fire. This disconnect between time periods and the means by which human impacts affect different regions to a different degree casts a level of doubt with regards to the metrics and means by which the authors of this particular article measure it against is somewhat worrisome due to the fact that the metrics by which the authors propose would necessarily have the individual believed that any and all forest fires are impacted upon by the very same mechanism.

Operating System Concepts - Assignment Example 2. Methods and Object Synchronization (mutual exclusion): One process should be able to use only one resource at a time. The request by another process should be delayed until the resource has been released. 3. Deadlock prevention: Deadlock can be prevented by using different schemes or by avoiding the necessary conditions (mutual exclusion, hold and wait, no preemption and circular wait (Stalling, 274)) which hold true for it. The different schemes are: 2. (20 points) Given that the first three necessary conditions for a deadlock are in place, provide detailed comments on the feasibility of the following strategy and the potential outcomes based upon its application. All processes are given unique priorities. When more than one process is waiting for a resource and the resource becomes available, allocate the resource to the waiting process with the highest priority. Now, in the given scenario all processes have their unique priority. Let us assume there are two resources R1 and R2 and process P1 has higher property than P2. Consider P1 holds R1 and P2 holds R2 and P2 is requesting for R1. Now, if P1 requests for R2 it will not get the resource even if it has the higher priority, because resources are not preemptive. So deadlock is still possible in this condition. There exists one CPU in this system, which may run one program at a time. Should information be allowed to move from any level to any level or should transfers only occur from adjacent levels? Explain in detail.

Provide support to manage pain and discomfort Essay Example for Free

Provide support to manage pain and discomfort Essay Agreed ways are a set of rules, regulations, policies and procedures set out by the company which are kept in the office and are always available to be accessed. Care plans, policies and procedures always have to be followed and necessary precautions have to be taken. Before using any kind of methods to manage pain, the resident/service user needs to be assessed has every kind of pain relief can be potentially harmful. Care plans are made individually for a specific person. Care plans are made to bring comfort and support It’s important to be aware of communication, both verbal and non-verbal. It’s important to always communicate slowly and clearly so that the resident can understand you. Always try to empathize with your resident, (empathize to see from their point. I would ask on a scale of 1 to 10, 10 being the highest, and 1 being the lowest, how the pain feels, by communicating you can find out their pain level then inform the Nurse who will then check to see if medication can be administered. Read more: Essay on Provide Support to Manage Pain and Discomfort If a resident cannot communicate verbally I would monitor their body language, i.e. face expressions, i.e. holding their hand, leg or limbs, this could be their way of expressing pain or by checking their turn charts, they might of been in the same position for a long time, i.e. on the left side for some time so by repositioning the resident your relieving them from discomfort and pain. I may be quiet difficult to express and communicate their pain i.e. said once but unclearly, you ask them to repeat themselves, they become angry and shout. Try to listen closely and clearly, it can be very difficult to concentrate energy to communicate, so any communication should be given 100% of your attention. All residents have different ways of communicating and different ways of understanding. All residents have different pain and discomfort levels. It’s important that we understand they are not being difficult or  awkward, just every resident has different types and ways of comfort and relief. Remember pain medication can cause anger and frustration verbally be aggressive cause confusion lack of concentration not able to make clear choices or decisions pain medication could also have an effect on their behaviour make them sleepy Always consider and respect a resident’s culture and religion. It’s very important to remember person centred care = care is designed around the individual not individual around the care. Remember the purpose is to bring pain free, comfort, dignity and peace to your resident.

Companies Need to Adopt Family-Friendly Policies Essay -- Feminism Fem

Companies Need to Adopt Family-Friendly Policies For the past 30 years, women have been under the gun to prove that they can be just like men in the workplace. Mainstream feminist groups believed this was the way to gain equality at work. Thus began mainstream feminists' support of abortion - eliminating pregnancy made women more like men. At the outset, this tactic appeared to work. Women proceeded to break down barriers and close in on equality. Business Week's Nov. 27, 2000, issue said that 45% of all managerial posts in the United States are held by women, and the World Bank's Development Indicators for 2000 show an average of female participation in the workforce of over 40%. Yet women are by no means equally represented at all levels of the workplace - Carleton "Carly" Fiorina of Hewlett Packard is the only female CEO in Forbes magazine's list of top 100 companies - and issues like sexual harassment and gender discrimination are still real barriers to too many women at work. Those who have a family feel they can be penalized even further. In a survey conducted as part of a Wall Street Journal study, 36% of respondents with children at home feared missing out on advancement while on maternity leave. Mainstream feminist organizations thought these problems would be solved by abortion, but abortion doesn't help women who choose to have children. "The workplace is still arranged, to a great degree, for workers who have no child-care responsibilities," says Serrin Foster, president of FFL. "Now, nearly three decades after Roe v. Wade, women are challenging the idea of abortion as the solution to inequality in the workplace, and instead asking for workplace conditions that don't force them to choose between... ...e assistance when working from home. But it can be well worth the investment to maintain career skills and contacts and avoid falling too far behind in the traditional career track. Parents say they want affordable child care, flexible work schedules, family-friendly tax reform, more leave time for both mothers and fathers and more part-time job options. It remains to be seen whether the shift toward a family-friendly workplace for both men and women will continue, or if it has stalled with abortion as the "answer." Even a century ago struggling employees facing the challenge of work and family often succumbed to the pressure through abortion. Emma Goldman wrote in Mother Earth in 1911, "So great is the misery of the working classes that seventeen abortions are committed in every one hundred pregnancies." Certainly in the new millennium we can do better.

Formal Outline Essay

INTRODUCTION Attention material: The world stopped getting warmer almost 16 years ago, according to new data released last week. The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures. This means that the plateau or pause in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years. Credibility material: The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we’ve already set into motion? While we struggle to figure it all out, the face of the Earth, as we know it—coasts, forests, farms, and snowcapped mountains—hangs in the balance. Thesis statement: Today I want to share what I†™ve learned about global warming and it’s causes. Preview: We need to consider causes, effects and dangers of global warming. (Transition: Let’s begin by understanding more about global warming.) BODY I. The Earth is warming and human activity is the primary cause. A. U.S. scientists said in the media January 19, 2012, about the influence of mankind on the state of global warming has increased from 18% to 51%. B. The primary way humans cause global warming is by burning fossil fuels. 1. When we drive or fly. 2. When we eat meat and Exotic Foods. 3. When we use electricity. 4. When You Move Into A New Development. (Transition: Now, from this it becomes clear why humans are the main cause of global warming, let’s examine its major effects) II. Global Warming effect information. A. The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. B. Some impacts from increasing temperatures are already happening. 1. Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. 2. Researcher Bill Fraser has tracked the decline of the Adà ©lie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years. 3. Sea level rise became faster over the last century. 4. Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas. 5. Precipitation (rain and snowfall) has increased across the globe, on average. 6. Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees. C. Other effects could happen later this century, if warming continues. 1. Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters). 2. Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years. (Transition: So now, we know about global warming effects, let’s see our future†¦and how we can fix it!?) III. Predicted Effects and Impacts of Global Warming. A. Future effects about global warming. 1. Increased spread of infectious diseases: â€Å"an increase in the number of people exposed to vector borne diseases (e.g. cholera) and an increase in heat stress mortality.† 2. Degraded water quality: â€Å"Projected climate change will tend to degrade water quality through higher water temperatures and increased pollutant load from runoff and overflows of waste facilities.† 3. More frequent and more intense heat waves, droughts, and tropical cyclones. B. Some basic predictions of global warming. 1. Global mean temperature should increase by between 1.4 and 5.8 C (2.5 to 10 F). 2. The sea level should rise by between 9 and 88 cm (3.5†³ to 35†³). (Transition: Finally, I want to tell you about the solution of this huge problem.) IV. Solutions to Global Warming. A. There is no single solution to global warming. 1. Boosting energy efficiency. 2. Greening transportation. 3. Revving up renewables 4. Phasing out fossil fuel electricityManaging forests and agriculture 5.Exploring nuclear 6.Developing and deploying new low-carbon and zero-carbon technologies. 7. Ensuring sustainable development CONCLUSION Summary statement: Some impacts—such as record high temperatures, melting glaciers, and severe flooding and droughts—are already becoming increasingly common across the country and around the world. However, there is much we can do to protect the health and economic well-being of current and future generations from the consequences of the heat-trapping emissions caused when we burn coal, oil, and gas to generate electricity, drive our cars, and fuel our businesses. Concluding remarks: Since 1880 the world has warmed by 0.75 degrees Celsius.
