Berkelium is a synthetic element that is created in nuclear testing labs due to its radioactivity. Berkelium was produced by Stanley Thompson, Glenn Seaborg, Kenneth Street and Albert Ghirorso working at UC Berkeley. It was discovered in 1949 by bombarding americium wth alpha particles using a cyclotron. It has no uses outside of scientific research. Since 1967 only one gram of Berkelium has been produced in the US. Berkelium whilst not having any uses has been combined with oxides and halogens. It is a solid metal at room temperature and it has a melting point of 986°c and a boiling point of 2900°c.
