Unformatted text preview: Types of Bonds: An Overview A. Bonds 1. All bonds involve valence electrons a. Electron in the outermost principal energy level. 2. Result from a variety of chemical reactions 3. All bonds involve a decrease in potential energy. a. Energy of bonded atoms is less than energy of free atoms. b. Formation of bonds involves a release in energy. 4. The Octet Rule and Bonds a. Atoms tend to gain, lose, and share electrons in order to acquire a full set of valence electrons. b. Most atoms have a full valence when they have eight valence electrons. c. The Noble Gases already have a full valence of eight electrons. 5. Types of Bonds: a. Ionic b. Covalent c. Metallic 6. Type of bond is dependant on differences in electronegativity: Electronegativity Difference Bond Type < 0.5 Nonpolar covalent Between 0.5 and 2.1 Polar covalent > 2.1 ionic B. Ionic Bonds 1. A bond between two or more elements that involves an exchange of electrons. exchange of electrons....
