In 1958, scientists at Lawrence Berkeley National Laboratory claimed the discovery of element 102, now called nobelium. At the same time, they also tried to synthesize element 103 by bombarding the same curium target used with nitrogen-14 ions.
This element had a controversial history of discovery. In 1958, the Lawrence Berkeley Laboratory (LBL) bombarded curium with nitrogen and appeared to get element 103, isotope-257. In 1960, they bombarded californium with boron hoping to get isotope-259 but the results were inconclusive.
Lawrencium (Lr), synthetic chemical element, the 14th member of the actinoid series of the periodic table, atomic number 103. Not occurring in nature, lawrencium (probably as the isotope lawrencium-257) was first produced (1961) by chemists Albert Ghiorso, T. Sikkeland, A.E. Larsh, and R.M. Latimer.
16 Οκτ 2013 · Discovery: Lawrencium was discovered at the University of California, Berkeley, by Albert Ghiorso, Torbjørn Sikkeland, Almon E. Larsh and Robert M. Latimer in 1961.
Chemical element number 103 was named lawrencium in his honor after its discovery at Berkeley in 1961. Early life. Ernest Orlando Lawrence was born in Canton, South Dakota, on August 8, 1901.
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).
29 Μαΐ 2018 · Lawrencium is a synthetic radioactive element and the last member of the actinide series. It was discovered in 1961 by Albert Ghiorso and his coworkers, who bombarded a target of isotopes of californium ( 249 Cf – 252 Cf) with boron projectiles (either 10 B or 11 B) using the Heavy Ion Linear Accelerator (HILAC) at the University of ...
