Research Elements Lv · atomic number 116 Post-transition metal · period 7, group 16 [Rn] 5f14 6d10 7s2 7p4 Shells: 2, 8, 18, 32, 32, 18, 6 Valence electrons: 6 in the outer shell (7s2 7p4) Predicted by calculation; not yet measured. Green dots are the outer shell's s and p electrons. Softer green dots are the d electrons of transition metals, and the d and f electrons of lanthanides and actinides: they often take part in bonding, but not always. Grey dots are the core. Configuration from relativistic calculations; NIST lists ground states up to element 108. No natural isotope with a defined abundance in NIST's Atomic Weights and Isotopic Compositions.Livermorium
