Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
Now letâs take a look at how these atoms and molecules hold together. Bonds hold atoms and molecules of substances together. There are several different kinds of bonds; the type of bond seen in elements and compounds depends on the chemical properties as well as the attractive forces governing the atoms and molecules.The three types of chemical bonds are Ionic bonds, Covalent bonds, and Polar covalent bonds.Chemists also recognize hydrogen bonds as a fourth form of chemical bond, though their properties align closely with the other types of bonds.ow letâs take a look at how these atoms and molecules hold together.
