Notes
In 1961, enough einsteinium was synthesized to prepare a macroscopic amount of 253Es. This sample weighed about 0.01 mg and was measured using a special balance. This material was then used to produce mendelevium.
Einsteinium is a radioactive rare earth metal named after Albert Einstein. It is of no commercial importance and only a few of its compounds are known.
