Other hydrogen compounds are covalent. Formation of Ionic Compounds Ionic compounds form extended three dimensional arrays of oppositely charged ions. Ionic compounds have high melting points because the coulomb force, which holds ionic compounds together, is strong. Formation of Ionic Compounds Coulomb’s Law describes the attraction of positive ions for negative ions due to the opposite charges. Formation of Ionic Compounds Small ions with high ionic charges have large Coulombic forces of attraction. Large ions with small ionic charges have small Coulombic forces of attraction. Use this information, plus the periodicity rules from Chapter 6, to arrange these compounds in

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....
