Question

The variable oxidation state are exhibited by the elements of 3d-series because: (A) They contain unpaired electrons in 3d (B) 4s-electrons are readily involved in bonding (C) Energy difference between 3d and 4s orbitals is small (D) 3d - electrons only are involved in bonding

Tardigrade Admin · Accepted Answer

As energy difference between 3 d and 4 s is small, both these electrons are involved in bonding. Hence the oxidation state exhibited are maximum.

Q. The variable oxidation state are exhibited by the elements of 3d-series because:

They contain unpaired electrons in 3d

4s-electrons are readily involved in bonding

Energy difference between 3d and 4s orbitals is small

3d - electrons only are involved in bonding

As energy difference between $3 d$ and $4 s$ is small, both these electrons are involved in bonding. Hence the oxidation state exhibited are maximum.
