Question 32

Metals and their Compounds

Metals of the first transition series have special properties which are different from those of groups I and II elements because they have partially filled

  1. A.s orbitals
  2. B.p orbitals
  3. C.d orbitals
  4. D.f orbitals
Show the answer and explanation

Answer: C (d orbitals)

Explanation

Transition metals have partly filled 3d orbitals, which give them variable valency, coloured ions and catalytic activity.
