A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, … See more The scientific definition of a "crystal" is based on the microscopic arrangement of atoms inside it, called the crystal structure.
