Question

What are the favourable factors for the formation of ionic bond?

Answer 1

Bond formation also depends upon the lattice energy of the compound formed. Hence, favourable factors for ionic bond formation are as follows: (i) Low ionization enthalpy of metal atom. (ii) High electron gain enthalpy (Δ eg H) of a non-metal atom.

Answer 2

Explanation:

1. Low ionisation enthalpy of element forming cation.
2. More negative electron gain enthalpy of element forming cation.
3. High lattice enthalpy of the ionic compound formed.
