The formula of a compound—such as CH4—indicates the types of atoms present, with subscripts representing the relative numbers of atoms (although the numeral 1 is never written).Water, which is a chemical compound of hydrogen and oxygen in the ratio two hydrogen atoms for every oxygen atom,...
The chemical formula of a molecule has symbols for all the elements present in it. It often uses a number at the left to represent the count of atoms that comprise the element. For instance, the chemical formula for water is H2O. It indicates that one molecule of water is composed of tw...
