In this lesson you learned about two types of bonds: nonpolar covalent and polar covalent. Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.
Non-polar and polar covalent bonds both belong to the three categories of polarity as well as the two types of covalent bonds. All three types (ionic, polar and non-polar) are classified as chemical bonds wherein there is a force (electronegativity) that allows the attraction of the atoms of two particular elements.
