MCQ
Ionic compounds are formed most easily with
- ALow electron affinity, high ionisation energy
- ✓High electron affinity, low ionisation energy
- CLow electron affinity, low ionisation energy
- DHigh electron affinity, high ionisation energy
✓
Answer
Correct option: B.
High electron affinity, low ionisation energy
b
(b) The formation of ionic bond depends upon easy formation of cation and anion. therefore the ionisation energy value of the metal atom should be low,
(b) The formation of ionic bond depends upon easy formation of cation and anion. therefore the ionisation energy value of the metal atom should be low,
so that it can easily form cation. on the other hand, the electron affinity value of the non-metal atom should be high so that it can easily form anion.
