The electronic configuration is 2,8,13,2. Thus, K, L, M and N shells will have 2,8,13,2 electrons respectively.
The element is manganese, a transition metal whose electronic configuration can also be represented as [Ar]3d54s2.
2 electrons are present in the N shell of the atom of an element with atomic number 25.
