Lawrencium is the final member of the actinide series. Actually, all the elements in the periodic table that have an atomic number greater than 92 (the number of uranium) are very radioactive and lawrencium is no exception. Lawrencium is a synthetic chemical element with the symbol Lr (formerly Lw) and atomic number 103. It decays into nobelium-262 through electron capture, mendelevium-258 through alpha decay or through spontaneous fission. One isomer and 11 isotopes of the element have been synthesized, and lawrencium-262 is the heaviest of them.
