4.6 Write the favourable factors for the formation of ionic bond.
Formation of ionic bond takes place by the transfer of one or more electrons from one atom to another.
So, ionic bond formation mainly depends upon the ease with which neutral atoms can lose or gain electrons.
The bond formation also depends upon the lattice energy of the compound formed.
Ionic bonds will be formed more easily between elements with comparatively low ionization enthalpies and elements with a comparatively high negative value of electron gain enthalpy.
