16 Οκτ 2013 · Lawrencium has 10 recognized isotopes. Its most stable is 262 Lr, with a half-life of about four hours. Uses of lawrencium. Because lawrencium has only been produced in small quantities, its...
Lawrencium is a synthetic element and is highly radioactive and unstable element. It is the last member of the actinide series of the periodic table. History and Discovery. Lawrencium was synthesized independently by team of scientist working at the Joint Institute for Nuclear Research (JINR), Dubna and American Lawrence Berkeley Laboratory (LBL).
A team of Soviet scientists at the Joint Institute for Nuclear Research in Dubna discovered (1965) lawrencium-256 (26-second half-life), which the Berkeley group later used in a study with approximately 1,500 atoms to show that lawrencium behaves more like the tripositive elements in the actinoid series than like predominantly dipositive nobeliu...
