Ionic solids :
i) In these crystalline solids constituent particles are cation or anion.
ii) All salts are crystalline ionic solids.
iii) In ionic solids ions are held together by strong elestrostatic force of attraction.
iv) The arrangment of ions depends on
a) Size of mtion and anion
b) The charge on the ions
c) The polarisability of anions
v) lonic solids are hard and brittle and have high mp. and b.p.
vi) in solid state they are non conductor but in molten state or in aqueous solution they conduct electricity due to free ions.
vii) They undergo distorion and fracture in crystal structure on applying shearing force.
