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. The chemical symbol for Americium is Am. Atomic Mass of Americium. Atomic mass of Americium is 243 u.
p. 241. ISBN 978-0-88173-351-8 . 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. Americium is produced when plutonium absorbs neutrons in nuclear reactors or during nuclear weapons tests.

Am-241 found in the environment is in the form of microscopic dust. When released into air, americium deposits particles in the soil and water. Small particles in air can travel far from the release site. In water, americium will stick to particles in the water or to the sediment at the bottom.

Americium is produced when plutonium absorbs neutrons in nuclear reactors and nuclear weapons tests.
Oct 3, 2017 Americium-241 (241Am) and Diamond with a magnetosphere contains 85% protons, 14% α particles, and 1% heavy ions radiating.
The presence of americium-241 in plutonium is determined by the original concentration of plutonium-241 and the sample age. Americium-241. General Names americium-241, Am-241 Protons 95 Neutrons 146 Nuclide data Americium has an atomic number of 95 (the number of protons in the nucleus of the americium atom).
Americium-241 decays mainly via alpha decay, with a weak gamma ray product.The α-decay is shown as follows: The α-decay energies are 5.486 MeV for 85% of the time (the one which is widely accepted for standard α-decay energy), 5.443 MeV for 13% of the time, and 5.388 MeV for the remaining 1%. The γ-ray energy is 59.5409 keV for the most part, with little amounts of other energies such as
