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. If only a + or − is …

Nov 18, 2025 · 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 …

Sep 4, 2019 · Ions are atoms or molecules that gain or lose electrons and carry an electrical charge. Cations are positively charged ions, while anions are negatively charged ions.

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.

Nov 20, 2021 · 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 …

Jul 12, 2023 · In chemistry, positively-charged ions are called cations and negatively-charged ions are called anions. Ions can exist in solutions or on their own depending on specific conditions, such as …

Discover what ions are, how they form, and why they matter in chemistry. Master ion concepts with Vedantu’s expert guidance.

Ions are atoms that have gained or lost electrons, resulting in a net electrical charge. When an atom loses electrons, it becomes a cation, which is a positively charged ion. Conversely, when an atom …

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.

Ions form when doing so minimizes the total potential energy of the chemical species involved in the chemical reaction. Often, this is achieved by allowing atoms of different elements to achieve a full …
