Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
Molecules are held together through a process called bonding. The  types of bonds and their configurations are largely responsible for  the properties of matter. Nitrogenous base pairs (adenine, thymine, cytosine, and guanine)  are held together by hydrogen bonds. They are held to each other by  the backbone of the double helix strucâ¦ture of DNA.
