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.
29 Μαΐ 2018 · lawrencium (symbol Lr) Radioactive metallic element, one of the actinide series. It was first made in 1961 at the University of California at Berkeley by bombarding californium with boron nuclei. It is named after the US physicist Ernest Lawrence who established the laboratory where it was produced.
