Americium is a synthetic chemical element; it has symbol Am and atomic number 95. It is radioactive and a transuranic member of the actinide series in the periodic table, located under the lanthanide element europium and was thus named after the Americas by analogy. [5] [6] [7]
Americium has an atomic number of 95 (the number of protons in the nucleus of the americium atom). ... Americium-243 has a mass of 243.06138 g/mol and a half-life of ...
Americium-241 (241 Am, Am-241) is an isotope of americium. Like all isotopes of americium, it is radioactive , with a half-life of 432.2 years . 241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste .
Similarly, americium (atomic number 95) was discovered in 1944–45 by Glenn T. Seaborg, James, Leon O. Morgan and Albert Ghiorso, working as part of the Manhattan Project. By bombarding plutonium neutrons in the 60-inch cyclotron at the University of California, Berkeley.

Americium (atomic number 95) was discovered in 1944-45 by Glenn T. Seaborg, Ralph A. James, Morgan, and Albert Ghiorso by bombarding plutonium-239, an isotope of plutonium, with high energy neutrons. This formed plutonium-240 , which was itself bombarded with neutrons, turning into plutonium-241 , which then decayed into americium-241 through ...

A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
