What are the conditions for formation of an electrovalent bond?
Conditions for formation of Ionic bond are:
(i) The atom which changes into cation should possess 1, 2 or 3 valency electrons. The other atom which changes into anion should possess 5, 6 or 7 electrons in the valence shell.
(ii) A high difference of electronegativity of the two atoms is necessary for the formation of an Ionic bond.
(iii) There must be an overall decrease in energy i.e., energy must be released.
For this an atom should have low value of Ionisation potential and the other atom should have high value of electron affinity.
(iv) Higher the lattice energy, greater will be the case of forming an ionic compound.
Answer:
The conditions for the formation of an electrovalent bond are as follows: The atom which changes into cation (+ ive ion) should possess 1,2 or 3 valency electrons. It will loose these electrons to form cation with +1,+2 or +3 charge.
