The strength of binding energy of transition elements depends upon:
Correct answer: B. Number of unpaired electrons
- A. Number of electron pairs
- B. Number of unpaired electrons
- C. Number of Neutrons
- D. Number of protons
Explanation
Number of unpaired electrons is correct because the strength of binding energy in transition elements primarily depends on the presence of unpaired electrons in the d orbitals. Unpaired electrons contribute significantly to the magnetic properties and reactivity of transition metals, making them crucial for forming strong bonds.

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.
