Answer:
Polyatomic ions are covalently bonded groups of atoms with a positive or negative charge caused by the formation of an ionic bond with another ion. Compounds formed from such ion combinations are called polyatomic ionic compounds, but the polyatomic ion behaves as a single unit.
Polyatomic ions and ionic compounds take part in chemical reactions such as acid-base, precipitation and displacement just like monatomic metallic ions. They dissolve in water, conduct electricity and dissociate in solution just like other ions. While they behave externally like monatomic ions, their internal structure is more complicated due to the presence of two or more atoms in the polyatomic ion.
