what do you mean by crystalline solid
Crystalline solids consist of atoms, ions and molecules arranged in definite and repeating three-dimensional patterns in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Crystalline solids, or crystals, have distinctive internal structures that in turn lead to distinctive flat surfaces, or faces
Crystalline substances can be described by the types of particles in them and the types of chemical bonding that takes place between the particles. There are four types of crystals: (1) ionic, (2) metallic, (3) covalent network, and (4) molecular
