Diagram showing field lines and equipotentials around an electron, a negatively charged particle. In an electrically neutral atom, the number of electrons is equal to the number of protons (which are positively charged), resulting in a net zero overall charge. Charge is the fundamental property of forms of matter that exhibit electrostatic attraction or repulsion in the presence of other matter.
and electrons have a negative electric charge: This means that if an atom has equal numbers of protons and electrons it will have no overall charge. When an atom loses an electron it must have more protons than electrons so it will have an overall positive charge: these are all positive ions.
