berkelium
Synthetic radioactive metal
Berkelium is a radioactive metallic element, atomic number 97, one of the actinides.
It was first synthesized in 1949 at the University of California, Berkeley, by bombarding americium with alpha particles.
Like other transuranium elements, berkelium has no practical applications outside scientific research and is produced only in minute quantities.
