An Atom is made up of 3 parts, protons, neutrons and electrons. Each element has it's own number of protons and electrons which will always be the same number. The protons and neutrons make up the nucleus of the atom, this sits in the centre with the electrons orbiting it. The Atom is mostly empty space as the nucleus takes up a tiny proportion of the atom.
