Anempirical formula consists of symbols representingelementsin acompound, such as Na forsodiumand Cl forchlorine, and subscripts indicating the relative number ofatomsof eachconstituentelement. (A subscript is not used, however, unless the number is more than one.) Thus,benzeneis represented by the...
For example, each oxygen molecule is made up of 2 oxygen atoms, and the chemical formula of oxygen is O2 Diatomic molecules, chemical forms: O2 (oxygen), N2 (nitrogen), H2 (hydrogen) F2 (fluorine gas), Cl2 (chlorine) and Br2 (liquid bromine) Chemical formula for polyatomic molecules: ...
