Answer 2

Answer:

i. There is a regularity and periodicity in the arrangement of constituent particles in crystalline solids. The ordered arrangement of particles extends over a long range.

ii. Crystalline solids have sharp melting points, that is, they melt at a definite temperature.

iii. All crystalline substances except those having cubic structure are anisotropic. In other words their properties like refractive index, thermal and electrical conductivity, etc, are different in different directions.
