MCQ
Ionic bonds are usually formed by combination of elements with
  • A
    High ionisation potential and low electron affinity
  • ✓
    Low ionisation potential and high electron affinity
  • C
    High ionisation potential and high electron affinity
  • D
    Low ionisation potential and low electron affinity
✓

Answer

Correct option: B.
Low ionisation potential and high electron affinity
b
Ionic bonds are formed by cation with low ionization energy and anion with high electron affinity so that anion can easily gain the the electron removed easily from the cation.
