Which of the following is typical transition metal?
Correct answer: D. Co
- A. Sc
- B. Y
- C. Cd
- D. Co
Explanation
Option D is correct since only Co is a typical transition element.Group 2B (Zn, Cd, and Hg) and group 3B(Sc, Y, and La) are nontypical transition elements.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
