Manganese (Mn) belongs to the transition metal series in the periodic table with an atomic number = 25
The electron configuration for Mn is:
1s² 2s²2p⁶ 3s²3p⁶ 4s² 3d⁵
The total number of 's' electrons = (1s,2s,3s,4s) = 8
Total number of 'p' electrons = (2p, 3p) = 12
(If one only considers the valence/outer electron configuration of Mn:
4s²3d⁵
then, number of s electrons = 2
number of p electrons = 0)
