Hi, and welcome to this video about molecules! Molecules are collections of covalently bonded atoms. They are the smallest unit in a covalent compound and determine the properties of the bulk substance. Ionic compounds do not have distinct molecular units and they are not considered molecules. Charged covalently bonded polyatomic substances are also not considered molecules by strict definition; however, many chemists relax the definition when it comes to these compounds. Molecules are formed during a chemical reaction when bonds are broken and reformed between atoms.
