- Ion - Wikipedia
Ions consisting of only a single atom are termed monatomic ions, atomic ions or simple ions, while ions consisting of two or more atoms are termed polyatomic ions or molecular ions
- Ion | Definition, Chemistry, Examples, Facts | Britannica
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges Positively charged ions are called cations; negatively charged ions, anions Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells
- What Is an Ion? Chemistry Definition - Science Notes and Projects
In chemical reactions, ions form when atoms or molecules gain or lose valence electrons Only nuclear reactions change the number of protons in a chemical species The two types of ions are anions and cations An anion has a net negative electrical charge It contains more electrons than protons

Ions are single charged atoms (simple ions) or small charged “molecules” (polyatomic ions) ” Simple ions include Na +, Ca 2+, and Cl – Polyatomic ions include (NH 4) +, (CO 3) 2-, and OH – Unlike protons and neutrons, electrons can be easily removed and added to an atom
