Concept:Electrovalent (ionic) bond formation depends on atomic properties that affect electron transfer.
Explanation:Ionic bonds form when one atom loses electrons and another gains them.
Key factors are electronegativity difference, electron affinity, and ionization potential.
Electronegativity attracts shared or transferred electrons.
Electron affinity measures the energy released when an atom gains an electron.
Ionization potential is the energy needed to remove an electron from an atom.
Catalytic ability only affects reaction speed, not the tendency to form an electrovalent bond.
Hence, catalytic ability does not influence electrovalent bond formation.
Answer:D. Catalytic ability
