Question -
Answer -
An ionic bond is formed bythe transfer of one or more electrons from one atom to another. Hence, theformation of ionic bonds depends upon the ease with which neutral atoms canlose or gain electrons. Bond formation also depends upon the lattice energy ofthe compound formed.
Hence, favourable factorsfor ionic bond formation are as follows:
(i) Low ionizationenthalpy of metal atom.
(ii) High electron gain enthalpy (Δeg H)of a non-metal atom.
(iii)High lattice energy of the compound formed.
