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 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 …

Nov 1, 2012 · Ions are formed when an atom lose or gain electrons. Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons.

In either case, they become 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 …
