The binding energy of transitional elements weakens progressively upto group:
Correct answer: C. IIB
- A. IIIB
- B. IV B
- C. IIB
- D. VB
Explanation
The binding energy of transitional elements weakens progressively up to Group IIB (Group 4) in the transition metals. As you move across a period, the atomic size decreases, resulting in weaker atomic bonding and, therefore, weaker binding energy.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
