MCQ
Transition metals are less reactive because of their:
  • A
    High ionization potential and low melting point.
  • ✓
    High ionization potential and high melting point.
  • C
    Low ionization potential and low melting point.
  • D
    Low ionization potential and high melting point.
✓

Answer

Correct option: B.
High ionization potential and high melting point.
Transition metals are less reactive relative to $I$ and $II$ group due to higher ionization potential and high melting point $($due to greater no of bonding electrons$).$
