A synthesized radioactive metallic element,
the last of the actinide series, symbol Lr,
atomic number 103, atomic weight 262. It has
a half-life of about a minute and was
originally synthesized at the University of
California at Berkeley in 1961 by bombarding
californium with boron nuclei. The original
symbol, Lw, was officially changed in 1963.
It was named after Ernest O Lawrence
(1901-58), American physicist, the inventor
of the cyclotron.
