How many s electrons and p electrons does mn possess?

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)

8s 12p Just took the quest or whatever its for you.

Explanation:

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
