I would like to work on the metal plutonium because the discovery of plutonium has a great impact on the world. Plutonium’s symbol is Pu and its atomic number is 94. This element has 150 neutrons and 94 protons and its standard atomic weigh is 244. Plutonium is located in the 7th period and it is a silvery white metal. One of its main uses is to act as the fuel of nuclear fission Plutonium does not exist naturally, although some say that small traces are found in the environment. So therefore, it is generally a man-made element. Plutonium was first discovered in a California university radiation laboratory by nuclear chemist and scientist Glenn T. Seaborg and his colleges. The first isotope of Plutonium found is Pu-238. An isotope of an element is basically different version of an element. The isotope number is the atomic mass of that particular version of the element. The number of neutrons determines different isotopes. For example Pu-244 have 94 protons with 150 neutrons; and Pu-239 have 94 protons with 145 neutrons. Because of the discovery of plutonium is in 1940 and World War 2 is happening at that time, discovery of plutonium was kept as a secret. In order to produce plutonium, uranium atoms must absorb neurons and it will decay into plutonium. One example of neutron absorption is nuclear fission, which will be explained below. Back in the time when plutonium is discovered, the US had a scheme called the Manhattan project. They built facilities that are used to produce plutonium from uranium. They lower the fuel rod, which is basically containers containing uranium, and they release the neutrons and they starts to bombard the uranium. That's one of the methods of plutonium production that is in use today still. Near the end of World War II, United states dropped 2 atomic bombs in Japan, one made from uranium and the other made from plutonium. The death toll was over 100,000 and there are even more...
