Livermorium

Element 116 · Post-Transition Metal

Livermorium is the group 16 transactinide, the superheavy counterpart of polonium. First produced in 2000 by a Russian-American team at Dubna, only a few dozen atoms have ever been observed, decaying within tens of milliseconds. Theory predicts it will be a dense metal favoring the +2 oxidation state. Properties are predicted, with very limited experimental data. Livermorium is intensely radioactive, decaying within tens of milliseconds.
