The binding energy of transition metal increases upto group:
Correct answer: D. VIB
- A. IIB
- B. IVB
- C. IIIB
- D. VIB
- E. No definite answer
Explanation
Binding energy is directly proportional to the number of unpaired electrons. And as we move from group IIIB to group VIB unpaired electrons increases after that pairing starts.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
