What is America?

America is an element with atomic number 95 and an atomic symbol AM. He was appointed for America analogy with Europio, which was named for Europe. Its atomic weight is 243. It has a whitish, silver color. The actinides, along with lanthanides, are classified as internal transition elements between metals. The American was the third of the ten elements that Seaborg participated in discovery. The actinide series has designed Seaborg and its concept of this group arose from the difficulties it experienced in the isolation of America and Curium, two elements he discovered at the University of Chicago. The unexpected problem lssed him to differentiate these elements from temporary metals and propose a new concept of the periodic table, which was first published in 1945. Every year only a few pounds are produced. It is limited to the laboratory because its high alpha radiation level is very dangerous. Its alpha radiation is about three times larger than alpha radiation Radium and also emits quite a lot of gamma radiation.

americium is used as a gauge in the glass industry, commercial smoke detectors and as a source of neutrons combined with other elements. Thanks to its role in smoke detectors, it is present in much more homes than any of the other synthetic elements. His gamma -ray emissions gave him a role in radiology; Although it was no longer used in this application today, it was suddenly used in the diagnosis of the thyroid function.
