Explain the characteristics of ionic solids.

(N/A) $1$. The constituent particles of ionic solids are ions.
$2$. These solids are formed by the three-dimensional arrangement of cations and anions bound by strong Coulombic (electrostatic) forces.
$3$. These solids are hard and brittle in nature and possess high melting and boiling points.
$4$. In the solid state,they are electrical insulators because the ions are not free to move. However,in the molten state or when dissolved in water,the ions become free to move,allowing them to conduct electricity.
