In this section we consider the second of our three types of strong atomic bonds. Covalent bonding is what we call the strong attraction that holds together the atoms of nonmetallic elements. Covalent bonding is associated with a great variety of materials. It is found in elements and in compounds. It is found in networks and in molecules. It is also found within the polyatomic ions. Essentially it is found in any material in which nonmetallic atoms are bonded together.
Linus Pauling, after whom our science buildings are named, was foremost among those chemists who worked on the problem of covalent bonding and how it works. Now that it has been figured out, it's really not very complicated.
In the pages of this section, we will look first at the basics of covalent bonding, how it applies to covalent compounds and other materials, and then at electronegativity.
