7, just like manganese, and the ReO4- (perrhenate) ion contains Re(VII) and has the same structure as MnO4- (permanganate).

The free atom has the configuration 6s2 5d5, but all of these count as valence electrons.

Valence Electrons are the electrons in the outermost shell. Rhenium has 2 Valence Electrons.

rhenium has seven valence electrons.

two of these are in a bonded pair, however and normally do not participate in bonding.
