The ions that we have discussed so far are called monatomic ions, that is, they are ions formed from only one atom. We also find many polyatomic ions. These ions, which act as discrete units, are electrically charged molecules (a group of bonded atoms with an overall charge). Some of the more important polyatomic ions are listed in Table 2.5.

Google Classroom Learn what polyatomic ions are and how they bond. Some ions consist of a single atom with a net charge. They're called monatomic ions. Examples include Na + , O 2 − , and Cl − . Other ions consist of a molecule —a group of atoms covalently bonded together—with a net charge. They're called polyatomic ions.

Polyatomic ions are formed when a group of atoms have a charge. Hydroxide, for example, is formed when oxygen and hydrogen covalently bond but still have a charge of -1. When a polyatomic ion forms an ionic bond with another ion, a polyatomic ionic compound is made. For example, the +1 barium ion can form an ionic bond with the -1 hydroxide ion, to form the Barium Hydroxide (BaOH) ionic compound.

A polyatomic ion (also known as a molecular ion) is a covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. [1] The term molecule may or may not be used to refer to a polyatomic ion, depending on the definition used.

Figure 3.6. 1: Polyatomic Ions Infographic. Polyatomic ions have defined formulas, names, and charges that cannot be modified in any way. Table 3.6. 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.
Complete List of Polyatomic Ions Physical Chemistry Physical Sciences
Polyatomic ions. 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 NH 4 + ), and hydronium ion ( H3O+ H 3 O + ); and anions like hydroxide ion ( OH− OH − ), and.

Table of Polyatomic Ions. There are a number of ions that are not individual atoms but are composed of multiple atoms that are covalently bonded together. However, this group of atoms is most stable when it has either lost of gained an electron and thus existed as a charged ion. These polyatomic ions are extremely common in chemistry and thus.
