Question

pictorial representation of any 3 ionic compounds

Answer 1

A+X- where A has partial positive charge and X has negative charge

Answer 2

Ionic compounds contains Ionic Bonds which are formed by transfer of electrons from one atom to another.
The transfer of ions takes place in such a way that the ions formed have a stable electron arrangement of inert gas.

1. Sodium Chloride :
Sodium metal reacts with chlorine to form an ionic compound called as Sodium Chloride.
Formation:
Na        ₋         e⁻ ---->    Na⁺
Sodium          electron    sodium ion
atom          
2,8,1                                 2,8

Cl                +   e   ---->     Cl⁻
Chlorine         electron     chloride ion
atom
2,8,7                                2,8,8  
Bond Formation :
Na⁺  +  Cl⁻  ---> NaCl
