Question

How many electrons can the 2nd shell accommodate?

Answer 1

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`
