Definition of Molecular Formula



There are various formulas that are used in order to represent a chemical compound or a molecule. One of those is a molecular formula. The molecular formula is one that is composed of the chemical symbols of the elements that are present in the compound. The numeric scripts are written along with the symbol of the element and they describe the number of atoms of that element.

 


The molecular formulas are very easy to understand but they do not provide us with information regarding bonding and the arrangement of the atoms. The molecular formulas may also include some extra information like brackets, plus and minus signs, etc.

 


Examples of Molecular Formula:

The molecular formulas of sodium chloride, glucose, potassium permanganate are NaCl, C6H12O6, KMnO4 respectively.
