Lawrencium (Lr) is an artificial chemical element, atomic number 103, solid, metal, period 7, the last element in the actinoids family, radioactive, unstable, obtained by nuclear reactions in particles accelerators.
Because lawrencium was obtained only in minutes amounts (1 000 - 2 000 atoms) the chemistry and physics of Lr are practically unknown. Lawrencium is trivalent in solutions and have now 11 isotopes. The longest half life is for Lr-266: 58 minutes. Some physical and chemical properties are only estimated.
