According to the different arrangement of atoms in matter, matter can be divided into two categories: crystalline and amorphous. A substance in which the atoms are regularly arranged is called a crystal. All solid metals are crystals. Substances with irregular arrangement of atoms inside are called amorphous. Such as glass, rosin, asphalt, etc. The regular
