Remember that we use chemical symbols to stand for the elements. For example, C stands for carbon, O stands for oxygen, S stands for sulphur and Na stands for sodium. For a molecule we use the chemical symbols of the atoms it contains to write down its formula. For example the formula for carbon monoxide is CO.It tells you that each molecule of carbon monoxide consists of one carbon atom joined to one oxygen atom.or a molecule we use the chemical symbols of the atoms it contains to write down its formula.
