The Atomic Structure Experiment

The "2nd U.S. Circuit Court of Appeals" held that those business practices that have had a disparate impact effect on the older workers are now considered to be actionable under one national anti-discrimination law (Hamblett, 2004). The case does reaffirm a second Circuit precedent that had been set but which is at odds with what a majority of federal courts have held. The appeals court supported the idea that a layoff plan had been properly brought under the The Age Discrimination in Employment Act of 1967 (ADEA) although the company did not have the intention of discriminating.

The popular or accepted version of this story is that it was all a made up story designed to put the military in a bad light to the citizens. The president of the United States at the time was President Franklin Roosevelt. Many people believe that Allende was among those that disliked Roosevelt and that Allende made up his story to stir up his presidency. Remember that Franklin D. Roosevelt is the only president in history to serve more than two terms so he was rightly one of our greatest presidents, but as all great leaders, he did have enemies. It is believed that Allende was part of a group that resented President F.D.R. especially because he served four terms, and wanted not only to take him out of office, but to make a stain on his good image.

Marie’s experiment and research had a massive impact on the atomic theory by discovering two new elements that have helped prove the existence of atoms and making the theory of it more believable for people. Her discovery had landed her multiply awards such as nobel prizes etc and Marie work in Chemistry will be remembered for a long time by her making a massive impact on science and help make the other scientist take women seriously in the all of the science departments.

What is an atom? An atom is the basic building block of everything. An atom is made of electrons protons and neutrons and the number of protons determines the element. Back in the 1800’s this whole idea was unknown. In the 1800’s steam was starting to power everything. It became important to know how steam works, so you can learn to use it more effectively. It was this idea that drove Dalton to research the atom.

During the early 1940’s atomic science had just began to mature. Many people were exploring the powerful mystery of the atom. Two of those people were Eugene Booth and John Dunning, who, in 1941, synthesized uranium-235. Immense scientific growth followed their contribution, since it allowed for nuclear fission (Griffith). In the years following this discovery, nuclear science took a turn. Once only used as a constructive power source, atoms began being explored for their destructive power. In 1942 the United States government funded the Manhattan Project that sole goal was to develop a nuclear bomb. The initiator for this endeavor was surprisingly the famous scientist Albert Einstein. He wrote to Franklin D. Roosevelt , and tipped him off

Thomson did many experiments and found that the mass of one of these electrons was nearly 2000 times lighter than the element Hydrogen. Thomson then disproved Dalton in stating that atoms cannot be divided into smaller pieces. (Born,

Throughout the course of his experiment, Rutherford had his two associates (Hans Geiger and Ernest Marsden) aim a beam of alpha particles at a piece of gold foil that was approximately 8.6 x 10^(-6) centimeters thick. To be more accurate Rutherford actually included a wide variety of different foils (such as: aluminum, iron, and lead), but his use of gold foil is most commonly spoke of. In accordance to the J.J. Thomson model of an atom, the alpha particles should have passed directly through the gold foil for all instances. Therefore to confirm this activity, a zinc sulfide screen was placed behind the foil as a backdrop for the alpha particles to appear upon. Directly above this screen was a microscope that allowed one of the two experimenters

The equation E = mc^2 were the roots of the Manhattan Project and without this equation, we would not have the nuclear weapons we have today. The Manhattan Project is by far the most significant event that occurred in World War II and is still relevant in physics today.

With all great inventions of man, it will always be used for bad before it is used for good. Before airplanes made it possible to go from New York to Tokyo in 7 hours, they were dropping bombs across the skies of Europe. Before man had touched the stars with the help from a rocket. Those very same rockets were delivering death and destruction in the form of missiles. The very same can be said about the discovery of nuclear energy. Scientists saw the good in the new source of energy, but their pay check comes from the men demanding weapons of mass destruction. The Manhattan project did bring us an end to the war, a new weapon, and the discovery of a new fundamental energy source. Without the push to develop it, nuclear energy likely wouldn't

Over the course of the last 5000 years, mankind’s knowledge has been constantly advancing. Chemistry, a branch of science, has experienced a tremendous leap and expansions since ancient Greek civilization. One of the major breakthroughs in the advancement in Chemistry was the creation of the Atomic theory, which laid a foundation for the modern-day Chemistry and future of science. The Atomic theory introduced the idea of atoms, which are defined as the discrete units of matter. There are five key scientists that significantly contributed to the Atomic model over a span of thousands of years. They are: Democritus, John Dalton, J.J. Thompson, Ernest Rutherford, and Niels Bohr.

After the war in Europe had ended, the United States’ needed to terminate their participation in World War II. In order to end the war, military action had to be taken against the Japanese so cause them to surrender. The only issue was finding a way to carry out an attack that would have low casualties and funding. During the war, the Japanese soldiers fought to the death, including mass suicides and attacks by kamikazes, or suicide bombings in planes. A land invasion, such as D-day, could have caused a large death toll on Japan, and also cause many Americans to lose their lives. The United States believed that to end the war they must make a critical blow to the Japanese. Thus the Hiroshima and Nagasaki bombings were born. The bombings

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

He positioned a variety of metal foil in the route of the alpha rays, including gold, silver, tin, copper and aluminium (at different times) to observe whether the flashes of light moved, spread out, or changed at all. He found that as the various metals disrupted the paths of the rays the flashes become more spread out. This result indicated that alpha particles were being deflected as they passed through the metals. Rutherford wanted to know if alpha particles could be deflected at a larger angle, as the current tool developed by Geiger could only measure deflection of up to a few angles.

Once upon a time, the atoms which make up everything, including our bodies, were formed in the stars. Most of those stars are dead now but they left us the most important legacy – atoms. Atoms are small particles which make up everything. From the chair you're sitting on, to the nails on your left hand, your funny nose you so desperately dislike. Those atoms, of course, form more complex structures which make us breathe, and run, and sleep, and read, and cry. They make up our life. Sadly, our atoms at one point become too tired of us and they want to escape. We may get sick, or be hit by a bus, or we may one day just not wake up. When they decide to leave us, there is no coming back. We die.

What is the atomic structure you may ask? Well, it’s the law stating the structure of an atom. It is composed of a positively charged nucleus containing a certain amount of protons (positive), neutrons (neutral charge), and electrons (negative). The amount of each subatomic particle (proton, neutron, and electron) all depend on what the element is. Now although this statement may seem fairly simple it was most definitely not. People have been studying the atomic structure for more than 300+ years and are still studying it. So after reading this you may wonder who even made this atomic structure up. After hundreds of years of research there is not any one individual who made the structure up but roughly
