Question

Factors favourable for the formation of ionic bond are:

• A. Number of valence electrons
• B. Draining of ionic enthalpy
• C. Low ionisation energy.
• D. All of the above

Answer 1

Answer: (A), (C)

The correct options are
A Number of valence electrons
C Low ionisation energy.

The following factors are favourable for the formation of ionic bond:
(i)Number of valence electrons
(ii) Low ionisation energy
(iii) Net lowering of energy
(iv) Attraction towards electrons
To form a stable ionic compound, there must be a net lowering of energy.
In other words, energy must be released as a result of electron transfer from one atom to another.
