Livermorium (Lv)

Unknown

Livermorium is a superheavy element named after Lawrence Livermore National Laboratory, and with [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁴, livermorium (half-life 53 milliseconds for Lv-293) is predicted to be more reactive than polonium. Only about 10 atoms have been produced, making its chemistry almost entirely theoretical.
