Crystalline solids are a class of solids that have regular or nearly-regular crystalline structures. This means that the atoms in these solids are arranged in an orderly manner. Solids are divided into two types:crystalline solids amorphous solidsThese two are differentiated on the basis of their physical properties. Crystalline solids are of a definite shape and have a definite melting point, while amorphous solid have no definite shape and melt at a range of temperatures. Crystalline solids are also known for their anisotropic nature, whereas amorphous solids are isotropic..
