Answer
The maximum number of that can be present in a shell is given by the formula 2n 2 where n is the number of shells.
Maximum number of electrons in a particular shell:

K (n = 1) |
2 x (1) 2 = 2 x 1 |
2 |

2 |
L (n = 2) |
2 x (2) 2 = 2 x 4 |
8 |

M (n = 3) |
2 x (3) 2 = 2 x 9 |
12 |
|
4 |
N (n = 4) |
2 x (4) 2 = 2 x 16 |
