Americium

Henry Szeto Name:Americium Symbol:Am Number:95 Atomic Mass: 243.0614 Am-243 has 95 proton/electron and 148 neutrons Electron Configuration:[RN] 5f7 7s2 Common Forms: it is a compund and it decay in to plutonium
 * __Americium__**

Physical Properties: Americium is a silvery and white substance. At room temperature it will beging to dissapear. It is also known to be more silvery than plutonium and nepunium. If anyone who handle it, they will have serious problem because it emits gamma ray. If the Americium is good enough people can make weapons out of it. Chemical Properties: It oxidize in air. it does not form a dioxide americyle core. In the environment could comples with carbon as well as oxygen and it will change in to the soil.

History: Americium was first discover by Glenn T. Seaborg, Leon O. Morgan, Ralph A. James, and Albert Ghiorso in the late 1944 at the Metallurgical Laboratory in the University of Chicago. It was World War 1 and the u.s government have a research site in which they created their first atomic bomb there. Glenn Seaborg and his team discover Americium through beta decay. It is named after America. Today it is known as a rare earth metal.



Uses: There are several uses for Americium. Stable Isotope: 241Am, 242mAm, 243Am The difference between these isotope is that their decay rate is really different and their half-life is different also. Their atomic mass is different and so is their feature. some of it has more radiation that the others.
