Question

If k, l, m and n shells of an atom are completely filled with electrons, what would be the total number of electrons in the atom?

Answer 1

The total number of electrons in the atom will be 60

2(1) square =2

2(2) square =8

2(3) square = 18

2(4) square = 32

2+8+18+32 =60

Answer 2

Answer:

The total number of electrons in an atom will be 32 electrons.

Explanation:

When K, L, M, N shell will be completely filled then the total number of electrons will be 32. Because after that electrons will be start repeating.

2n^2, n=1, electron= 2*1*1 = 2. K shell

2n^2, n=2, electron= 2*2*2 = 8. L shell

2n^2, n=3, electron= 2*3*3 = 18. M shell

2n^2, n=4, electron= 2*4*4 = 32. N shell
