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.

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. …

Sep 4, 2019 · Learn the definition of an ion, as used in chemistry, chemical engineering, and physics, plus review examples of 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.

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.

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 …

Atoms form ions to achieve a more stable electron configuration, typically that of the nearest noble gas. By losing or gaining electrons, an atom can attain a full outermost electron shell (an …

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 …

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.

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