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. The prefix poly- carries the meaning "many" in Greek, but even ions of two atoms are commonly described as polyatomic. In older literature, a polyatomic ion may instead be referred to as a radical or less commonly, as a radical group. In contemporary usage, the term radical refers to various free radicals , which are species that have an unpaired electron and need not be charged. Polyatomic ions often are useful in the context of acid—base chemistry and in the formation of salts.

Define a polyatomic ion

The same reason monatomic ions have a charge - due to an imbalance between the number of protons and electrons. Polyatomic ions are composed of two or more covalently bonded atoms - similar to that of a neutral molecule. However, as the name implies, this group of covalently bonded atoms has a difference in the number of electrons v protons. So in the formation of the cyanide ion, for example, CN-, carbon and nitrogen bond together through the formation of a carbon-nitrogen triple bond. However, if we draw the appropriate structure, you will see that in order for the carbon and nitrogen to achieve stable electron configurations, they will need one more electron than the two of them have collectively - so they obtain an additional electron from a metal donor. This video may help:. Poly atomic ions are covalent compounds that have an overall charge and therefore are held together through the electrostatic attraction of ionic bonding to positively charged ions called cations.
