Compounds can be represented in two main ways:

Chemical Formula and Molecular Model

The types of Chemical formula include:

Empirical formula, molecular formula, and structural formula

 

Types of Molecular model include:

Ball and stick model, and space-filling model.


There are so many different methods because each method specifies a specific aspect about a compound.

For example, the empirical formula gives the relative number of atoms of each element.

The molecular formul gives the actual number of atoms in a molecule

Structural formul shows how they're bonded to one another.

Ball and stick model shows the geometry of the molecule.

Space-filing model helps give an idea about the relative sizes of the atoms of a compound.
