Einsteinium has 153 neutrons, 99 protons, and 99 electrons. It's atomic mass is 252 and its shells are 2, 8, 18, 32, 29, 8, 2. Its chemical symbol is Es. Einsteinium has 19 isotopes; each isotope has a different number of neutrons.
The most important isotope - Es-253, has a half life of 20,47 days.The longest half life is for the isotope Es-252: 471,7 days.But einsteinium has 19 isotopes and 3 isomers, each with a different half life.
Einsteinium was discovered in the debris of 'Mike',the code name for the first thermonuclear explosion witch took place on Eniwetok,a Pacific atoll,on 1 November 1952...'Mike' was the precursor to the development of a thermonuclear weapon, the so-called hydrogen bomb. (THAT was dumb, but it was worth discovering element 99 between californium and fermium...)
Californium applications - neutron source to start-up nuclear reactors (Cf-252) - neutron source for neutron diffraction instruments (Cf-252) - neutron source for neutron spectroscopy instruments (Cf-252) - raw material for the preparation of heavier chemical elements (Cf-249) - source for portable neutron activation instruments (Cf-252) - source for radiation therapy with neutrons (Cf-252) - source for neutron radiography (Cf-252) - source for moisture detectors (Cf-252) - source for gold and silver detectors (Cf-252) - source for analysis instruments of coals, cements etc. (Cf-252)
Use the formula (F - 32)/9 = C/5 That is (F - 32)/9 = (252/5) Find F
