Ionic compounds are formed most easily with

Options

A. Low electron affinity, high ionisation energy
B. High electron affinity, low ionisation energy
C. Low electron affinity, low ionisation energy
D. High electron affinity, High ionisation energy

Answer

B

Explanation

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.
