OXIDATION NUMBERS (p23) OXIDATION RULES 1.fluorine is always -1 2.The rest of the halogens chlorine, bromine and iodine usually -1, unless they bind with oxygen or fluorine - then we will have to work out their oxidation numbers 3.Hydrogen is usually +1 unless it binds with a metal, then it is - 1 4.OXYGEN is usually -2, except it is -1 in H 2 O 2 and O 2 2- and +1 if it binds with fluorine 5.Group 1 is always +1 6.Group 2 is always +2 7.The most electronegative element always has the negative oxidation number 8.Neutral diatomic molecules such as H 2 and Cl 2 's oxidation number is 0 9.Isolated ions’ oxidation number is equal to the charge according to the periodic table
