Why are Zn, Cd, Hg, and Cn not regarded as transition elements?

Options

  1. AThey have incomplete d orbitals
  2. BThey have completely filled d orbitals
  3. CThey have a variety of oxidation states
  4. DThey exhibit paramagnetic behaviour

Correct answer

B. They have completely filled d orbitals

Step-by-step solution

Zn, Cd, Hg, and Cn are not regarded as transition elements because their d orbitals are completely filled in the ground state as well as in their common oxidation states.
