Q. Statement 1: Transition metals show variable valence.
Statement 2: Due to a large energy difference between the $ns^{2}$ and $\left(n-1\right) d$ electrons.

The d-and f-Block Elements

Solution:

The statement 1 is correct but the statement 2 is false. Actually transition metal show variable valency due to very small difference between the $ns^2$ and $\left(n + 1\right) d$ electrons
