KI = 0 because KI is a compound which means its o.n. is always 0
Always +1 in all its compounds
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
KCLO3 the oxidation number of potassuim is +1, oxidation number of chlorine is +5 the oxidation number of oxygen is -2 and there are 3 atoms of oxygen KClO3=1+5+(-2)3=0 therefore the oxidation number of KClO3 =0 or neutral
+1 for K -2 for each O +5 for N
K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7
the oxidation number of each K is +1. But there are two K's so 1*2 is +2. the charge on the molecule has to equal 0, so the oxidation number of the S must be -2.

+1 for K and -1 for Cl
+1 for K -1 for F
+1 for each K, -3 for N
+1 for K, -1 for Br
K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7
as oxidation number of K is 1 and the molecule is neutral 1+ Cl=0 Cl= -1 Therefore, the oxidation number of Cl is -1
0 in elemental form; +1 in all its compounds
