Find out the maximum number of electrons that can be accommodate in m sell using 2n² rule​

Answer is

Explanation:

There are mainly four shells in an atom namely K, L, M, and N.

By using 2n², we can find the maximum number of electrons present in M shell.

Let, K = 1st shell, L = 2nd shell, M = 3rd shell, and N = 4th shell.

K = 1, L = 2, M = 3 and N = 4.

K = 2n² = 2(1)² = 2(1) = 2.

L = 2n² = 2(2)² = 2(2) = 4.

M = 2n² = 2(3)² = 2(9) = 18.

N = 2n² = 2(4)² = 2(16) = 32.

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

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
