Neutrons and protons make up the nucleus of an atom. They make up the mass of the atom. The volume of an atom is made up of electrons which move outside the nucleus Describe the parts of the atom and where they are found. Neutral atoms have the same number of electons (negative) and protons (positive).
The nucleus contains two kinds of particles: neutrons, which have no charge, and positively charged protons. Negatively charged particles called electrons orbit around the nucleus in different layers, or orbitals. (Unlike this diagram, there is a vast space between the nucleus and the electron orbitals.
