Question

is ionic bond ? write all favourable conditions for the formation of ionic bond ?

Answer 1

Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. The ions are atoms that have gained one or more electrons and atoms that have lost one or more electrons.
Two elements must be of opposite charge.

• An element must have its less Ionisation Enthalpy(Cation).

• Another element must have high negative electron gain enthalpy(Anion).

• Difference of Electronegativity between two Elements much be greater than or equal to 1.7

• High lattice energy of the compound formed.

These are the conditions for the formation of ionic bond.

Answer 2

The favourable conditions for forming stable ionic bond are : (i) Lowionization enthalpy of element forming cation. (ii) More negative electron gain enthalpy of element forming anion.
