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.

Ions are single charged atoms (simple ions) or small charged “molecules” (polyatomic ions).” Simple ions include Na +, Ca 2+, and Cl –. Polyatomic ions include (NH 4) +, (CO 3) 2-, and …

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 …

Jul 12, 2023 · What Is An Ion In Chemistry? An ion is an atom that has an electric charge because it’s either lost or gained one or more of its electrons. In chemistry, positively-charged …

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.

Making an ion from an atom or molecule is called ionization. Two or more ions can combine to make a chemical compound. The link between the ions is called an ionic bond. The charge on …
