A model aids in visualizing a molecule and understanding its properties.
In chemistry, models of molecules give us an idea about the arrangement of atoms in the molecules. Usually, the arrangement of atoms in a molecules determines the kind of reactions that the molecule can undergo.
Models are three dimensional representations of what molecules look like. They help us to conceptualize the possible orientation of atoms and groups in the molecule.
Looking at the model of H2SO4, it becomes easier to understand the chemical and physical properties of the compound owing to the arrangement of atoms.
