Why the electronic configuration of calcium is 2,8,8,2 why not 2,8,10 as 3rd shell can holds 18 electrons

Answers

Answered by hariomugalegmailcom

Answer:

Calcium =2,8,8,2 and 28,10 both

Explanation:

Why? (K)=2, (L)= 8 (M)=18 (N)=32. This electronic configuration formula.

Answered by rohitsingh1818

According to the 2-8-8 rule, the 3rd orbital has only 8 electrons in its valence orbital, but from the formula 2n^2, the 3rd shell would have 18 electrons in its valence orbital.
