Each element is made up of one kind of atom.
Every element is made up of electrons (negative), protons (positive) and neutrons (neutral). Only protons and neutrons have mass. Electrons orbit the nucleus which contains protons and neutrons.
Elements are made up of only one type of atom. This means that they consist of atoms all with the same number of protons. The number of neutrons, however, can vary within an element; this is called isomerism.
