Unformatted text preview: order of increasing attractions among ions KCl, Al 2 O 3 , CaO You do it! Covalent Bonding Covalent bonds are formed when atoms share electrons. If the atoms share 2 electrons a single covalent bond is formed. If the atoms share 4 electrons a double covalent bond is formed. If the atoms share 6 electrons a triple covalent bond is formed. The attraction between the electrons is electrostatic in nature The atoms have a lower potential energy when bound. Formation of Covalent Bonds This figure shows the potential energy of an H 2 molecule as a function of the distance between the two H atoms....
