Electronic configuration of of Tellurium

Te: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p4Te5+:1s22s22p63s23p64s23d104p65s24d95p0

Same electronic configuration has an ion of Tellurium +5 and Cd+1, In+2

The order of filling the shells with electrons of Tellurium (Te5+): 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’

Tellurium has 52 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

9 electrons on 4d-sub level

Oxidation state of Tellurium

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

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 Te5+ = 5

Ions of Tellurium

Valence of Te5+

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

Valence of Tellurium is an ability of an atom Te 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 Te 5+

Quantum numbers are defined by the last electron in configuration, for an ion Te these numbers are N = 4, L = 2, Ml = 1, Ms = -½
