The meaning of ION is an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons. How to use ion in a sentence.

In contrast, ions are atoms or assemblies of atoms that have a net electrical charge. Ions that contain fewer electrons than protons have a net positive charge and are called cations. Conversely, ions that contain more electrons than protons have a net negative charge and are called anions.
The resulting charged species is called an ion. Cations and anions. When a neutral atom loses one or more electrons, the total number of electrons decreases while the number of protons in the nucleus remains the same. The result is that the atom becomes a cation —an ion with a net positive charge. The opposite process can also occur.
