And:- 8 #e^-#

Explanation:

We all know that electrons are filled in the shells by the formula
number of electrons# = 2n^2#

And #n# is the number of the shell you are looking for.
For eg: k =1st shell
L = 2nd shell
M = 3rd shell
So n = 1 for k
2 for L
3 for M
And so on.
So for n=2
We get number of electron = #2**2^2#
#=8#
