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.
Another example of a nonpolar covalent bond is the bond between two chlorine atoms because they also equally share the electrons. Nonpolar covalent bonds are very strong bonds requiring a large amount of energy to break the bond.n a polar covalent bond, the electrons are not equally shared because one atom spends more time with the electrons than the other atom. In polar covalent bonds, one atom has a stronger pull than the other atom and attracts electrons.
