Which of the following element is not a transition element?(a) Fe(b) Mn(c) Zn(d) AgThis question was addressed to me during an interview.The question is from Position of the Periodic Table topic in portion D and F-Block Elements of Chemistry – Class 12

Answer»

The correct CHOICE is (c) Zn

Best explanation: All transition elements are d-block elements, but all d-block elements are not transition elements. ZINC has the electronic CONFIGURATION [Ar] 3d^104s^2, and the configuration of the Zn^2+ ION is [Ar] 3d^10. THUS, both the element and its only known stable ion have completely filled d-orbitals. Also, the metal does not exhibit any variable valency or multiple oxidation states in compound formation.
