Which of the following is the common oxidation state for 'transition' elements?

Which of the following is the common oxidation state for 'transition' elements?
  1. +3
  2. +1
  3. +2
  4. +4

Solution

Transition metals commonly exhibit +2 oxidation state because only two electrons can exist in an \(s\)-orbital, and removing the electrons from the sub shell below it requires immense amounts of energy, this limits them to a +2 charge most of the time. Hence, the correct option is (c). ,
