1.

Give reasons for the following:Transition metals show variable oxidation states.Actinoids show variable oxidation states.

Answer»
  1. Since (n-1)d and ns orbitals takes part in bond formation due to their comparable energy, transition elements show variable oxidation states.
  2. It is due to comparable energy of 5f, 6d and 7s orbital, any member of electron can participate to bond formation so actionoids show variable oxidation state.
