Americium 241 protons neutrons electrons

Americium-241 (95 2 41 Am ) is an isotope Plutonium-239 was bombarded by neutrons to form plutonium-240. When this isotope was itself subjected to neutron bombardment plutonium-241 was formed. The plutonium-241 decayed by beta decay to form americium-241 which has a half life of 432.2 years and decays by alpha decay. A number of other isotopes of americium have now been made. If you look at the periodic table, the atomic number of americium is 95, indicating that it has both 95 protons and 95 electrons. The 241 is the mass number, which is equal to the number of protons Americium-241 decays mainly via alpha decay, with a weak gamma ray byproduct. 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 2%.

95 electrons (assuming no charge) *** Therefore, 95 protons * (1.007276u) + 146 neutrons * (1.008664u) + 95 electrons * (0.00054858u) = 243.00828u, which is the "predicted" mass. The isotope mass of Americium-241 is 241.056829144u.

Th Alpha particles are actually helium nuclei (two protons and two neutrons). Relatively large Americium (Am-241) Curium (Cm-241) + ejected electron. Gamma  Positron Emission (β decay) and Electron Capture An alpha particle is composed of two protons and two neutrons and is the same as a Inside a smoke detector, Am-241 emits α particles that ionize the air, creating a small electric Atoms have protons and neutrons in the center, making the nucleus, while the electrons orbit the nucleus. Neutral atoms have the same number of electrons as they have protons, Americium-241 is an isotope used in smoke detectors. Complete the nuclear equation below for the decay of Am-241.
