アインスタイニウムの同位体
1. Isotopes of einsteiniumEinsteinium (Es) is an artificial element, and thus a standard atomic mass cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be discovered was Es in 1952. There are 19 known radioisotopes from Es to Es, and 3 nuclear isomers (Es, Es, and Es) The longest-lived isotope is Es with a half-life of 471.7 days.
