Chapter 5 Type of Bonds and Representations: Types of Bonds: o Ionic (between metal and nonmetal ions) o Covalent (shared) bonds Representations (Ex: Hydrogen Peroxide): o Empirical formula HO o Molecular formula H 2 2 o Structural Formula H-O-O-H  Valence Electrons: Outer shell electrons of an atom that participate in chemical bonding o o NOTICE HOW WHEN YOU GO DOWN THE ROW, THEY ARE THE EXACT SAME (EXCEPT HELIUM)!! The Ionic Bond:  Ionic Bond: electrostatic force that holds ions together in an ionic compound Electrostatic (Lattice) Energy:  Lattice energy (U): energy required to completely separate one mole of a solid ionic
