Some ions consist of groups of atoms covalently bonded together and have an overall electric charge. Because these ions contain more than one atom, they are called polyatomic ions. The structures, names, and formulas of some polyatomic ions are found in the below figure and table. Figure \(\PageIndex{1}\): Polyatomic Ions Infographic
Polyatomic ions are charged molecules made of two or more ions. The entire molecule has an overall charge. It is important not only to be able to identify and name the ion but also to remember the ion's charge.

2 sie 2022 · Polyatomic ion definition: A polyatomic ion is an ion composed of two or more atoms. A polyatomic ion has either a positive charge (cation) or negative charge (anion). Examples: The hydroxide cation (OH -) and the phosphate cation (PO 43-) are both polyatomic ions. Cite this Article.
11 wrz 2024 · Polyatomic ions have defined formulas, names, and charges that cannot be modified in any way. Table 3.4.1 lists the ion names and ion formulas of the most common polyatomic ions. For example, NO − 3 is the nitrate ion; it has one nitrogen atom and three oxygen atoms and an overall 1− charge.
Polyatomic ions are molecular ions composed of two or more atoms bonded by covalent bonds and acting as a single unit, but unlike molecules, they have a net charge on them. The examples include cations like ammonium ion (NH+4), and hydronium ion (H3O+); and anions like hydroxide ion (OH−), and cyanide ion (CN−).
