What is the characteristic of oxidation state variability in transition elements related to the filling of d orbitals?

Options

  1. ATheir oxidation states differ by a unit of two
  2. BTheir oxidation states differ by a unit of three
  3. CTheir oxidation states differ by a unit of four
  4. DTheir oxidation states differ by unity

Correct answer

D. Their oxidation states differ by unity

Step-by-step solution

The characteristic of oxidation state variability in transition elements arises out of incomplete filling of d orbitals in such a way that their oxidation states differ from each other by unity.
