Document Summary

Oxidation # of atoms add up to charge of molecule : oxidation # of atom in elemental form = o. C - i: flour in e = - 1. Halogens - except w/ oxygen: oxygen = - 2, hydrogen = -11 w/ except w/ f- to urine or peroxides ( o = t ) nonmetals but = - l w/ metals. = 5 - z - 3=0 ( group valence ) - ( lone pairs ) - i # of bonds ) oxidation # of nitrogen = charge on molecule - ( known oxidations ) = o - ( t 3) = - 3. Oxidation of s = i -21 - ( 4 x - 21. = +6 o: - i o oxidation - reduction reactions. 2nd is , t az cg ) 2 nacl is , oxidation : I use of oxidation numbers : h : always -11. O - 2: o , c : - 4 4.
