Electronic configuration of of Tungsten

W: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d4W+:1s22s22p63s23p64s23d104p65s24d105p66s24f145d3

Same electronic configuration has an ion of Tungsten +1 and Ta, Re+2, Os+3, Ir+4

The order of filling the shells with electrons of Tungsten (W+): 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’

Tungsten has 74 electrons, let's fill electronic layers in described order:

2 electrons on 1s-sub level

2 electrons on 2s-sub level

6 electrons on 2p-sub level

2 electrons on 3s-sub level

6 electrons on 3p-sub level

2 electrons on 4s-sub level

10 electrons on 3d-sub level

6 electrons on 4p-sub level

2 electrons on 5s-sub level

10 electrons on 4d-sub level

6 electrons on 5p-sub level

2 electrons on 6s-sub level

14 electrons on 4f-sub level

3 electrons on 5d-sub level

Oxidation state of Tungsten

Atoms of Tungsten in compounds have an oxidation state of 6, 5, 4, 3, 2, 1, 0, -1, -2, -4.

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 W+ = 1

Ions of Tungsten

Valence of W+

Atoms of Tungsten in compounds have valence VI, V, IV, III, II, I.

Valence of Tungsten is an ability of an atom W 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 W 1+

Quantum numbers are defined by the last electron in configuration, for an ion W these numbers are N = 5, L = 2, Ml = 0, Ms = +½
