Chapter 18—Oxidation-Reduction Reactions Pri__ I. Section 18.1—Oxidation Reduction Reactions A. Avery common type of reaction where electrons are transferred from one atom (or group of atoms) to another. B. When ametal and ano__etal react the metal gives some electrons to the no__etal and they form an ionic compound C. The metal is “oxidized” D. The no__etal is “redu__d” E. Oxidation =a loss of electrons Reduction= F. again of electrons II. Section 18.2—Oxidation States A. Electron Transfer is more difficult to see when the redox reaction involves 2or more non metals B. To __ke this easier we give “i__ginary” charges to the atoms in covalent compounds C. Oxygen is apart of all redox reactions involving no__etals Oxygen =-2 D. (the peroxide ex__ption!) Hydrogen =+1 E. electronegativity F. Oxidation states depend on the of the atoms involved 1. The more electronegative element always controls the electrons 2. The most electronegative elements are F>O>N>Cl
