About the Molecule Zone

A molecule is the smallest amount of a chemical substance that can exist. They are made up of atoms that are stuck together in a particular form. In gases like air, molecules are just flying around.

In liquids like water, molecules are stuck together but can still move around, which lets us pour liquids. In solids like sugar, the molecules are stuck together and can only vibrate.

This is a general chemistry zone, where you will meet chemists based in Scotland.
