Look at the number of bonding domains. for example, Calcium has a charge of +2 and oxygen has a charge of -2. They bond, and calcium gives up 2 electrons to the same oxygen, creating a double bond, forming a binary compound (Calcium Oxide) It all depends on the elements. The main thing is the number of electrons being transfered.
Nonpolar bonds mostly exist between atoms of the same element. For example, oxygen contains six electrons in its outer shell. To gain a full outer shell of eight electrons, oxygen atoms form double bonds with other oxygen atoms. Because they are identical atoms, they share the four electrons equally. When atoms of two different elements share electrons, they form polar covalent bonds. In polar covalent bonds, the shared electrons spend more of their time near one atom than the other, resulting in an uneven sharing and a partial charge on both atoms in the bond. Water is an example of a polar covalent bond.
