Step 1

In this model, atoms are represented by spheres and the bonds between them are represented by rods. For example, in the case of water (H2O), the hydrogen atoms can be represented by red spheres and the oxygen atom can be represented by a white sphere. The bonds Show more…

Key Concepts

Space-Filling Model

This model represents atoms as spheres scaled to their van der Waals radii, showing how the atoms occupy space within a molecule. By depicting the true volume and spatial arrangement of the atoms, it provides a more realistic representation of the molecule's overall shape and density, highlighting the molecule’s three-dimensional structure.

Ball and Stick Model

This model uses spheres to represent atoms and sticks to represent the bonds between them. It emphasizes the connectivity and angles between atoms, allowing a clear visualization of the molecular geometry while distinguishing between different types of atoms, typically through color-coding or size variations. This model is particularly useful for understanding the structure and bonding within molecules.
