Question

The maximum number of electrons present in M-shell of an element:
A) 5
B) 8
C) 12
D) 18

Answer 1

Answer:

18 electrons present in the M-shell

Answer 2

Answer:

D 18

formula for calculating is 2(n)^2,where n is the no. of electrons..

For K shell 2(1)^2=2

L shell 2(2)^2=8

M shell 2(3)^2=18

N shell 2(4)^2=32
