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.
For most covalent substances, their bond character falls between these two extremes. Bond polarity is a useful concept for describing the sharing of electrons between atoms . A nonpolar covalent bond is one in which the electrons are shared equally between two atoms ; A polar covalent bond is one in which one atom has a greater attraction for the electrons than the other atom. If this relative attraction is great enough, then the bond is an ionic bond; Electronegativity
