Ionic Solid|Summary

In ionic solids, the oppositely charged ions are closely packed in space and have strong electrostatic forces of attraction. These compound have high melting and boiling points and are poor conductors of electricity in the solid state. (i) Why are ionic solids poor conductros of electricity ? (ii) What happens to electrical conductivity when these are dissolved in water ?

Structure OF Ionic Solids

Assertion (A) : A tetrahedral void is surrounded by six spheres. Reason (R) : In ionic solids, the bigger ions form the close packed structure and smaller ions occupy the voids.

In which of the following solids, cations occupy tetrahedral voids ?
