The chemical element of atomic number 103, a radioactive metal of the actinide series. Lawrencium does not occur naturally and was first made by bombarding californium with boron nuclei.
- ‘Actinides - the radioactive chemical elements that span from actinium to lawrencium on the periodic table - have generated a great deal of interest in recent years.’
- ‘No one could really argue with the choice of lawrencium for element 103, after the man who had invented the machine for element synthesis.’
- ‘Due to its short half-life, there's no reason for considering the effects of lawrencium in the environment.’
- ‘Only a few atoms of lawrencium have ever been made.’
- ‘In 1968, Thiorso and associates at Berkeley used a few atoms of this isotope to study the oxidation behavior of lawrencium.’
1960s modern Latin, named after the American physicist E. O. Lawrence (see Lawrence, Ernest Orlando), who founded the laboratory in which it was produced.
