How many meta states does the first isotope to be synthesized in Am in 1944 have?
Isotopes of americium Americium (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 Am in 1944. The artificial element decays into alpha particles. Americium has an atomic number of 95 (the number of protons in the nucleus of the americium atom).
Isotopes of germanium Germanium (Ge) has five naturally occurring isotopes, Ge, Ge, Ge, Ge, and Ge. Of these, Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 years (130 billion times the age of the universe).
