ATOM Subatomic particles of an atom

Atoms are made up of tiny particles called subatomic particles.

An atom contains three types of subatomic particles: proton, electron and neutron

The proton and neutron form the nucleus at the centre of an atom. They are also called the nucleon of an atom.

The nucleus is positively charged because of the presence of protons, which are positively charged. The neutrons are neutral.

The electron moves around the nucleus at a very high speed.
