Oxidation state of Oganesson

Atoms of Oganesson in compounds have an oxidation state of .

The oxidation state is the conditional charge of an atom in a compound: the bond in a molecule between atoms is based on the sharing of electrons, thus, if the atom’s charge virtually increases, then the oxidation state is negative (electrons carry a negative charge), if the charge decreases, then the oxidation state is positive.

Valence of Og

Atoms of Oganesson in compounds have valence .

Valence of Oganesson is an ability of an atom Og to build chemical bounds. The valence is based on electronic configuration of atom: electrons participated in chemical bounds are known as valence electrons. In general the valence is:

The number of possible chemical bounds with other atoms

The valence has no sign.

Quantum numbers Og

Quantum numbers are defined by the last electron in configuration, for an atom Og these numbers are N = 7, L = 1, M_l = 1, M_s = -½
