Lawrencium is not a naturally occurring element. it was synthesized in 1961 by Albert Ghiorso, Torbjorn Sikkeland, Almon Larsh and Robert Latimer. It was the very last of the actinide series to be discovered. Californium was bombarded and hence, lawrencium was created. It was named after Ernest Lawrence, who invented the cyclotron particle accelerator.
Lawrencium is highly radioactive and has to be handled and stored very carefully. Currently, it has only been produced in small amounts but it is still very dangerous. It is only useful for scientific purposes.
