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%. View this answer An atom of americium-241 will have 95 protons and 146 neutrons located in its nucleus. We can determine this using the isotope number, which is also See full answer below.

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.

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 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 . Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas.

D. Both electrons and neutrons are deflected, but protons are not affected. E. Both protons and electrons are deflected, but neutrons are not affected. 21. Americium-241 is used in household smoke detectors. This element has 11 known isotopes, none of which occurs in nature, but must be made in the laboratory. Giv… Plutonium-239 was bombarded by neutrons to form plutonium-240.

Nov 5, 2016 Americium-241 was directly obtained from plutonium upon absorption of one neutron. A thorium atom has 90 protons and therefore 90 electrons, of which Thorium-232 (232Th), which has 142 neutrons, is the most stable&
