Description
Named after Albert Einstein, einsteinium is a highly radioactive metal. It was discovered in the radioactive fallout of a 1952 atomic bomb test. It has never been found naturally and less than a gram is produced each year. Its chemistry and appearance are not known with any certainty but should be similar to the other actinides. Einsteinium is too rare to have any commercial or industrial application. The most stable isotope of einsteinium has a half-life of 1.3 years.
Biological Benefits
