Why are transition elements different from non-transition elements?

Options

  1. AThey have different atomic numbers.
  2. BThey have different chemical reactivity.
  3. CThey have partly filled d or f orbitals.
  4. DThey have different valence electrons.

Correct answer

C. They have partly filled d or f orbitals.

Step-by-step solution

Transition elements are different from non-transition elements because of the presence of partly filled d or f orbitals in their atoms.
