How many the maximum number of electrons that can be accommodated in a shell. |
|
Answer» The maximum number of electrons that can be accommodated in a shell depends on the formula 2n2 where 'n' is the number of the given shell from the nucleus. For example, K Shell - 2 x (1)2 = 2, 1st period = 2 elements. L Shell - 2 x (2)2 = 8, 2nd period = 8 elements. M Shell - 2 x (3)2 = 18, but the outermost shell can have only 8 electrons, so the third period also has only 8 elements. |
