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

Options

  1. A+3
  2. B+1
  3. C+2
  4. D+4

Correct answer

C. +2

Step-by-step 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).
