Normally, an atom has an equal number of protons in the nucleus and electrons in its orbitals - hence an overall charge of zero. If it loses one or more electrons in a chemical or physical reaction, it is called an ion and has an overall positive charge.

Losing an Electron If an atom loses an electron, it becomes a positive ion. This is because the number of protons in the nucleus is greater than the number of electrons surrounding the nucleus. The net charge of the atom is therefore positive.
