Models of atoms and compounds help in understanding of concepts of reactions in chemistry.
<h3>What are models?</h3>
Models are objects used to provide a visual representation of certain things or structures.
Models are widely employed in chemistry because of their usefulness in strengthening understanding of concepts.
The importance of models in chemistry include:
- they help students to be able to visualize the structures of atoms and compounds in a macroscopic scale
- they provide an a clearer understand of how atoms combine to form products in reactions.
Therefore, models help in understanding of concepts of reactions in chemistry.
