Which of the following is the common oxidation state for 'transition' elements?
Options
- A+3
- B+1
- C+2
- 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).
