Einsteinium Element Cube

Description

Made In USA
2x2x2 inches
Radioactive symbol. No sample.
Named in honor of Albert Einstein, Einsteinium's atomic number is 99 and its symbol is Es. It is a soft, silvery, paramagnetic metal, and its chemistry is typical of the late actinides. The high radioactivity of einsteinium-253 produces a visible glow and rapidly damages its crystalline metal lattice, with released heat of about 1000 watts per gram.
It was discovered as a component of the debris of the first hydrogen bomb explosion in 1952. Its most common isotope einsteinium-253 (half-life 20.47 days) is produced artificially from decay of californium-253 in a few dedicated high-power nuclear reactors with a total yield on the order of one milligram per year.
