Isotopes vary only in their number of neutrons, not in their number of protons. Americium (chemical symbol Am) is a man-made radioactive metal that is solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors or during nuclear weapons tests.

It adheres very strongly to soil, with americium concentrations associated with sandy soil particles estimated to be 1,900 times higher Výroba. Americium-241 bylo v malých množstvích vyráběno v jaderných reaktorech po desítky let, již jej bylo vyrobeno mnoho kilogramů. Poprvé bylo nabídnuto k prodeji v roce 1962, ovšem jeho cena, kolem 1 500 USD za gram, se od té doby téměř nezměnila kvůli velmi složitému separačnímu procesu. Se hela listan på encyclopedia.com Atomic Number of Americium. Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure.

Americium was first made late in 1944 at the University of Chicago by a team which included Glenn Seaborg, Ralph James, Leon Morgan, and Albert Ghiorso. The americium was produced by bombarding plutonium with neutrons in a nuclear reactor. This produced isotope americium-241, which has a half-life of this is 432 years.

This isotope also has one meta state, 241mAm, with an excitation energy of 2.2 MeV and a half-life of 1.23 μs. The presence of americium-241 in plutonium is determined by the original concentration of plutonium-241 and the sample age.

Wiki has it in a box on the right side of the page. https://en.wikipedia.org/wiki/Americium-241. According to Wiki, this Americium: Atomic number: 95: Atomic mass [amu] 243: Atomic mass [pm] 180: Density at STP [g/cm3] 13.78: Number of protons: 95: Number of neutrons (typical isotopes) 241-243: Number of electrons: 95: Electron configuration [Rn] 5f7 7s2: Oxidation states +3,4,5,6: Electron affinity [kJ/mol] — Electronegativity [Pauling scale] 1.3: First ionization energy [eV] 5.9933 Americium ( 95 Am) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no known stable isotopes. The first isotope to be synthesized was 241 Am in 1944.
