The order of filling the shells with electrons of Bismuth (Bi⁵⁺): 1s → 2s → 2p → 3s → 3p → 4s → 3d → 4p → 5s → 4d → 5p → 6s → 4f → 5d → 6p → 7s → 5f → 6d → 7p.

On the sub level ‘s’ there might be 2 electrons at most, on ‘p’ - up to 6, on ‘d’ - up to 10 and up to 14 on ‘f’

Oxidation state of Bismuth

Atoms of Bismuth in compounds have an oxidation state of 5, 3, 1, -3.

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.

Oxidation state of an ion Bi⁵⁺ = 5

Ions of Bismuth

Valence of Bi⁵⁺

Atoms of Bismuth in compounds have valence V, III, I.

Valence of Bismuth is an ability of an atom Bi 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 Bi ⁵⁺

Quantum numbers are defined by the last electron in configuration, for an ion Bi these numbers are N = 5, L = 2, M_l = 0, M_s = -½
