Text Solution

Verified by Experts

The favourable factors for the formation of ionic bonds are :
(i) Low ionization enthalpy of the metal atom.
(ii) High electron gain enthalpy of the metal atom.
(ii) High electron gain enthalpy of the non - metal atom.
(iii) High lattice enthalpy of the compound formed.
