A nonpolar covalent bond is a covalent bond in which the electrons are shared equally between the two atoms. This type of bond is typically found between atoms of the same element, such as in the diatomic molecule H2. Nonpolar covalent bonds are also found in molecules such as CH4 and CCl4. To identify a nonpolar covalent bond, you need to look at the difference in electronegativity between the two atoms. If the difference is small (less than 0.5), then the bond is likely to be nonpolar covalent.
