Ball And Stick Model - GCSE Chemistry Definition

Reviewed by: Philippa Platt

Last updated

The ball and stick model is a visual representation used in chemistry to depict the structure of molecules. In this model, atoms are represented as spheres or "balls" and the chemical bonds connecting them are represented as "sticks". This method helps students studying GCSE Chemistry understand how atoms are arranged in a molecule and how they connect with each other.

The model emphasises the angles and dimensions of bonds, aiding in the comprehension of molecular geometry. While not entirely to scale, as the size of the balls and length of the sticks are exaggerated for clarity, the ball and stick model is an effective tool for visualising the three-dimensional structure of complex molecules.
