Revise: Size, Mass, and IsotopesAn ion has an overall charge because electrons have been lost or gained. Forming an ion does not change the number of protons or neutrons, so the atomic number and mass number stay the same.
- Revise: Metals and Non-Metals
An atom or group of atoms with an overall electrical charge because it has lost or gained electrons.
- Revise: Group 1 Alkali Metals
An atom or group of atoms with an electrical charge because it has lost or gained electrons.
