Models help us to understand the properties of molecules and help us to predict the kind of reactions they undergo.
A molecular model is a three dimensional representation of a molecule. Usually, molecular models could either be;
- Ball and stick models or
- Space filling models.
In either case, the model gives us a vivid representation of the molecule and enables us to predict its properties and reactivity based on the the inter-connectivity of atoms in the structure as shown in the model. The model of H2SO4 as shown gives us an idea of its properties and its reactivity.
