Question

write the formula which is used to determine the maximum no of electron that a shell can accommodate​

Answer 1

Answer:

Rule 1: The maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2)2 = 8 electrons.

Answer 2

2n^2 , is the answer for your question
