Question

the maximum number of electron that can be accomidate in the m-shell of an atom​

Answer 1

Answer:

So, the maximum number of electrons present in the M shell is 18.

Explanation:

The maximum number of electron that can accommodate in a shell is given by the formula 2n2

M shell n=3, hence M can accommodate 18 electron.

electrons are present in the M-shell and 2 electrons are present in the N shell. Hence, 8 electrons are present in the M-shell of an element with atomic number 20.
