Transition metals possess variable oxidation states because they have
-
Electrons in the d orbitals
- Electron in the s orbitals
- A variable number of electrons in the p orbitals
- Partially filled p orbitals
The correct answer is: A
Explanation
Transition metals have variable oxidation states because their valence electrons are in orbitals with similar energies, allowing them to be used for bond formation in multiple ways. Transition metals have partially filled d-orbitals in their outer electron shell.
