Description
There are several main types of atomic models in use today. Two of the most common are 'ball and spoke' and 'space-filling' types. Each model type displays different information about molecules. Whilst ball and spoke models are designed to show how the atoms bond together, space-filling models accurately demonstrate the size and shape of the molecule. The Courtauld Atomic Model set is a ‘space-filling’ type. Chemistry students use space-filling models to help when visualising whether the shape of certain bulky structures will prevent them reacting with other molecules. One disadvantage of space-filling type is that the model does not clearly demonstrate how the atoms bond together. This model set was made by Griffin and George, a company that designed mass-produced models for students learning chemistry. Griffin and George's Courtauld Atomic Models set is extremely well known amongst students of the period. It was developed from the designs of Dr. G. S. Hartley of Courtaulds Ltd. in 1952 and underwent several improvements over the next fourteen years.

The models themselves are made of a rigid plastic, with a colour scheme that is different from the recommendations set out by the Institute of Physics. Instead, the colours of these models were chosen for how good they would look in black and white photographs. The set comes with scale cards by Gallenkamp for estimating the size of the molecules (20mm equivalent to 0.1nm).
