A bond between the two ions are formed from the transfer of one electron to another. Which is generally form between a metal and non-metal. For example NaCl. ( Sodium chloride ). This is often described as one atom giving electron to the other. In the case of NaCl , Sodium would give electron to chlorine.
Ionic compounds dissociate into their ions when they dissolve in water. It will react a good conductors of electricity in aqueous solution.
PROPERTIES OF IONIC COMPOUND:
Due to strong force of attraction, all ionic compounds are exist in solid state. At room temperature forming a crystal lattice structure.
THERMAL STABILITY :
Ionic compounds have high melting point ( m.p) and boiling point (b.p )
They are strong electrolytes. In solid state they do not conduct electricity. In molten state and in aqueous solution they conduct electricity.
Generally ionic compounds are soluble in water and insoluble in organic compounds.
They are very hard.
Ionic compounds are very reactive .
THERMAL CONDUCTIVITY :
Ionic compounds are low thermal conductivity.
- Most of the ionic compounds are brittle and break under stress. Because ions produced by electron transfer attract each other by electrostatic attraction and this creates an ionic bond.
