Same electronic configuration has an ion of Rhenium +6 and Tm, Hf+3, Ta+4, W+5, Os+7
The order of filling the shells with electrons of Rhenium (Re6+): 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’
Rhenium has 75 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
13 electrons on 4f-sub level
Oxidation state of Rhenium
Atoms of Rhenium in compounds have an oxidation state of 7, 6, 5, 4, 3, 2, 1, 0, -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 Re6+ = 6

Valence of Re6+
Atoms of Rhenium in compounds have valence VII, VI, V, IV, III, II, I.
Valence of Rhenium is an ability of an atom Re 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 Re 6+
Quantum numbers are defined by the last electron in configuration, for an ion Re these numbers are N = 4, L = 3, Ml = 2, Ms = -½
