Answer 2

Answer : $4d^35s^2$ belongs to group 5 of the periodic table.

Explanation:

We are given an electronic configuration : $4d^35s^2$

To know the group of this configuration, we need to find the number of valence electrons. As, the configuration has d-electrons so, the number of valence electrons will be equal to the Group number.

Number of valence electrons = 5

So. group number = 5

This configuration belongs to Niobium element.

Hence, $4d^35s^2$ belongs to group 5 of the periodic table.
