El berkelio es un elemento sintético bautizado en honor a Berkeley, California. Se produjo por primera vez en 1949 en la Universidad de California.

Acerca de Berkelio

Berkelium takes its name from Berkeley, California, where the element was first produced in 1949 at the University of California. It is a synthetic actinide of atomic number 97 with a relative atomic mass of 247.0, a configuration of [Rn] 5f9 7s2, and an electronegativity of 1.3. Under standard conditions it is a solid. Like the actinides immediately around it, berkelium exists only in quantities made deliberately by neutron irradiation or accelerator bombardment, and the total mass ever prepared is measured in fractions of a gram. Its practical significance lies in nuclear synthesis rather than chemistry: berkelium targets have served as the starting material from which still heavier elements were subsequently created.
