Reduction-oxidation. Therefore, its the equations for oxidation and reduction. 1 of 10 What is oxidation? What is reduction? Oxidation is the lose of electrons while reduction is the gain. 2 of 10 What is oxidation states? In an ionic compound, it simply tells us how many electrons it has lost or gained compared with the element in its uncombined state. 3 of 10 What is every element in its uncombined state? oxidation state of 0 4 of 10 What should a compound always equal if a charge sign is not on it? 0 5 of 10 What is Hydrogens oxidation state? Unless? +1 unless in metal hydrides where it is -1 6 of 10 Group 1? 2? 3? +1, +2, +2 7 of 10 Al? +3 8 of 10 O? Unless? -2 (except in preoxide where it is -1 and OF2 where it is +2) 9 of 10 F? Cl? -1 10 of 10
