Understand the differences between Crystalline and Amorphous Solids. Click on the link to Watch the VIDEO explanation: Watch Video
There are two main classes of solids namely crystalline and amorphous. Click on the links to know more. Crystalline solids have a regular and repetitive patterns of atoms, molecules or ions. They are symmetrical shape flat smooth and plane faces which meet at a characteristic angle. They are classified as single crystal and poly crystalline crystals. If the periodicity of pattern is extended throughout the pattern then it is called single crystal solid. In poly crystalline crystals the periodicity of the pattern is interrupted at the boundaries. Crystalline solids have sharp melting points and all bonds have same strength. Diamond, rock salt, mica and sugar belong to this category. In amorphous solids, like liquids, the atoms and molecules are not arranged in an orderly manner. But in amorphous solids atoms are rigidly fixed and they are allowed to move as in liquids. Glass is an amorphous solid.
