All about Atoms
Everything around you, including air, water and your own body, is made of tiny particles called atoms. Atoms are so small that millions of them could fit on the head of a pin.
An atom has a central nucleus made of protons and neutrons, with electrons moving around it. Atoms of the same element all have the same number of protons. Atoms join together in groups called molecules to make all the substances we know.
