These were then used in the studies of thermal-neutron induced fission of 257 Fm, and in discovery of a new fermium isotope . 258 Fm.
22.
Einsteinium and fermium were discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the radioactive debris from the detonation of the first hydrogen bomb.
23.
Of the actinides, environment; analysis of debris from a 1952 hydrogen bomb explosion showed the presence of americium, curium, berkelium, californium, einsteinium and fermium.
24.
They were plutonium, americium ( used today in smoke detectors ), curium ( used in medicine ), berkelium, californium, einsteinium, fermium, mendelevium and nobelium.
25.
Fermium ( III ) can be fairly easily reduced to fermium ( II ), for example with samarium ( II ) chloride, with which fermium ( II ) coprecipitates.
26.
Fermium ( III ) can be fairly easily reduced to fermium ( II ), for example with samarium ( II ) chloride, with which fermium ( II ) coprecipitates.
27.
Fermium ( III ) can be fairly easily reduced to fermium ( II ), for example with samarium ( II ) chloride, with which fermium ( II ) coprecipitates.
28.
Cation-exchange and solvent extraction studies led to the conclusion that mendelevium was a trivalent actinide with an ionic radius somewhat smaller than that of the previous actinide, fermium.
29.
Owing to the small amounts of produced fermium and all of its isotopes having relatively short half-lives, there are currently no uses for it outside of basic scientific research.
30.
The isotopes discovered were einsteinium-253, with a half-life of 20.5 days, and fermium-255, with a half-life of about 20 hours.
