The two electrons in the 4s orbital are obvious valence electrons, so a valence state of 2+ is possible. Manganese is a transition metal, meaning that it can have more than one valence state. The electronic configuration of manganese is [Ar] 3d5 4s2. The element manganese has seven valence electrons. The atomic number of manganese is 25 and it has 25 electrons out of which seven electrons are in the last shell or orbit.

These are the electrons, the 4s2 3d5 electrons, in its outer or valence shell. A link can be found below.

Manganese is a transition element and exists in several oxidation states: +2, +3, +4, +6 and +7.

The symbol of manganese is Mn and its atomic weight is 54.938044 atomic mass units or grams per mole.

It has 7 valence electrons from its 4s^2 3d^5 configuration.

Its electron configuration is [Ar] 3d5 4s2.
