A chemical formula combines two or more symbols and it represents a chemical compound. We notice that the chemical symbols are followed oftenly by a subscript that represents the mole proprtions of next element. Chemical equation involve chemical formulas of reactants and products.
In order to make it easier to describe elements and molecules, chemical formulas are used. For example, H represents one atom of hydrogen and O represents one atom of oxygen. If we want to represent two atoms of hydrogen, instead of writing H H, we write H2.The subscript 2 means that two atoms of the element hydrogen have joined together to form a molecule.A subscript is only used when more than one atom is being represented. The graphic below illustrates the formula for water using symbols. Some more common molecules and their chemical formula.eview: 1  Chemical formulas are used to describe the types of atoms and their numbers in an element or compound. 2  The atoms of each element are represented by one or two different letters. 3  When more than one atom of a specific element is found in a molecule, a subscript is used to indicate this in the chemical formula.
