How many electrons neutrons and protons are in the nucleus of einsteinium?
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.
What is einsteinium half life?
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.
How did einsteinium get its name?
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...)
Why is the element californium important?
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)
What is 252 Celsius in Fahrenheit?
Use the formula (F - 32)/9 = C/5 That is (F - 32)/9 = (252/5) Find F
What is the atomic mass of einsteinium?
The atomic mass of einsteinium is 252. It is a synthetic element with the symbol Es and atomic number 99.
How is Einsteinium created?
