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 + …

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 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.

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 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 …

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

May 21, 2024 · There are three types -- anions, which are negatively charged, cations, which are positively charged, and radicals, or radical ions, which are highly reactive due to having a large …

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 …

Read this tutorial to learn about what an ion is, the differently charged ions, and how they are involved in different branches of chemistry!

Ions are atoms that have a charge due to an unbalanced number of protons and electrons. Anions have a negative charge, and cations have a positive charge.
