WebbCovalent bonds are chemical bonds that are formed when two nonmetal atoms share one or more pairs of electrons. The octet rule is an incredibly simple scientific hypothesis. It states that atoms tend to share or transfer electrons because this helps them get eight valence electrons and the same electron configuration as a noble gas atom.
