- 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

- 11. 4: Ions and Ion Formation - Chemistry LibreTexts
Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons If atoms lose electrons, they become positive ions, or cations
- Ions Information | Mount Sinai - New York
An ion is an atom or group of atoms that has an electric charge Ions with a positive charge are called cations Ions with a negative charge are called anions Many normal substances exist in the body as ions Common examples include sodium, potassium, calcium, chloride, and bicarbonate These substances are known as electrolytes Ions can be created using radiation such as x-rays Ionizing
- “An ion is a small electrically charged particle. Ions are single . . .
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
