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.
In chemistry, the definition of an ion is an electrically charged atom or molecule. This means the atom or molecule has an unequal number of protons and electrons. Neutrons carry no net electrical charge, so they don’t affect ions directly. In chemical reactions, ions form when atoms or molecules gain or lose valence electrons. Only nuclear ...
Electron transfer between lithium (Li) and fluorine (F). Forming an ionic bond, Li and F become Li + and F − ions. An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge.
What is an Ion? An ion can be defined as a chemical species which holds a positive or negative charge of some magnitude. The term ‘ion’ can be used to refer to atoms or molecules that have non-zero net charges associated with them.
An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species.
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.

An ion is an atom or molecule with either a positive or negative electrical charge. An ion has a charge because the number of protons does not equal the number of electrons; to find the number of protons and electrons, check out this article.
What is an Ion? An ion is an atom or molecule that carries an electric charge. Ions are identified by the use of a superscript to show the sign and size of their electric charge. Negatively charged ions are called anions, and positively charged ions are called cations.
What is an ion? In GCSE chemistry, an ion is an electrically charged atom which is formed by the loss or gain of electrons. Atoms lose or gain electrons to obtain full outer shells of electrons. If an atom loses electrons, it will form positively charged ions (cations), and if it gains electrons it will form negatively charged ions (anions).
