Nihonium: properties of free atoms
Nihonium atoms have 113 electrons and the shell structure is 184.108.40.206.32.18.3.
The ground state electron configuration of ground state gaseous neutral nihonium is [Rn].5f14.6d10.7s2.7p1 (a guess based upon that of thallium) and the term symbol is 2P1/2 (a guess based upon guessed electronic structure).
