Answers

Answered by skftvishwaa

That is not period that is shell
Actually the reason is third shell as per the rule must contain 18 elements because in its spdf configuration 4s2 is not third shell so 10 electrons are transfered to next shell
Therefore it contains only eight electrons.

skftvishwaa: Ok?
