Question

Period of element with outermost shell configuration 4s2 4p3

Answer 1

Answer : The period of an element is 4.

Explanation :

The outermost shell configuration of an element is $4s^24p^3$.

According to the electronic configuration given, It tells us about the valence shell of the element which is 4.

In modern periodic table, period tells us about the valence shell of the elements falling in that particular period.

So, the period of an element with outermost shell configuration $4s^24p^3$ is 4.
