Web14 nov. 2024 · Mass numbers of typical isotopes of Lawrencium are 254-256,259-262,266. Atomic mass of Lawrencium is 262 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Post navigation Lawrencium (103Lr) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was Lr in 1961. There are fourteen known isotopes from Lr to Lr, and seven isomers. The longest-lived known isotope is Lr with a half-life of 11 hours.
