Manganese has 25 electrons. Hope this helps. :)

Mn has 25 protons.
In actuality Mn has SEVEN valence electrons, not really 2 as might be predicted. The reason for this is that Mn is [Ar]3d5 4s2, and as a transition element, not only are the 4s electrons available for bonding, but so are those in the d orbital. So, the 5 electrons in 3d and the 2 electrons in 4s are all considered as valence electrons.
Mn2+ has 25 electrons. Mn2+ means that the manganese atom has lost two electrons, resulting in a +2 charge. Mn is the symbol for manganese, which has an atomic number of 25, indicating that it normally has 25 electrons in its neutral state.
It varies across the group e.g. Sc = 3 Ti = 4 V = 5 Cr = 6 Mn = 7
One Mn atom contains 5 electrons in it's 3d subshell, all of which are unpaired.

The Bohr diagram for Mn shows 4 rings because manganese has 25 electrons. Following the rule of placing 2 electrons in the first ring, 8 electrons in the second ring, 8 electrons in the third ring, and the remaining 7 electrons in the fourth ring gives a total of 25 electrons distributed in the 4 rings.
Manganese is a metal so it is monatomic, meaning 1 atom.

Mn is configured: [Ar] 4s2 3d5 , soMn2+ has an electron configuration of: [Ar] 4s0 3d5It looks like that 5 or 3 or (at least) 1 (one) electrons are to be unpaired.
