The two types of ions are anions and cations. 1. An anion has a net negative electrical charge. It contains more electrons than protons. For example, a chlorine atom with 17 protons and 18 electrons (Cl–) is an anion. An anion may be larger than its original atom if it gains an additional electron shell. 2. A cation has a net positive electrical ch...
Chemical notation indicates ions by following an element symbol or chemical formula with a superscript that shows whether a charge is positive (+) or negative (-) and the amount of charge. If an electrical charge is 1, only list the “+” or “-” symbol. Here are some ion examples: 1. H+ 2. Ca2+ 3. Fe2+ 4. Fe3+ 5. Cl– 6. P3- 7. NH4+ 8. H3O+ 9. HCO3– 1...
An ion containing only one atom is a monatomic ion. Examples of monatomic ions include H+, O2-, and Cl–. An ion containing multiple ions is a polyatomic ion or molecular ion. Examples of polyatomic ions are ammonium (NH4+), hydronium (H3O+), chlorate (CO3–), and hydroxide (OH–).
The word ion comes from the Greek word ion or ienai, meaning “to go.” English physicist and chemist Michael Faraday coined the term in 1834 as a way of describing the way a chemical species travels from one electrode to another in an aqueous solution. While Faraday did not identify the nature of the particles moving between electrodes, he saw metal...

“An ion is a small electrically charged particle. 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.
