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.
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
0 in elemental form; +1 in all its compounds
In K₂CrO₄, the oxidation number of potassium (K) is +1, and the oxidation number of oxygen (O) is -2. Since the compound is neutral, the oxidation number of chromium (Cr) can be calculated as follows: 2(+1) + Cr + 4(-2) = 0. Solving for chromium, the oxidation number of chromium in K₂CrO₄ is +6.
The oxidation number for Cl in KClO3 is +5. This is because oxygen has an oxidation number of -2 and potassium has an oxidation number of +1, so the total oxidation numbers must add up to zero for the compound.

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
In KO2, O has an oxidation number of -1, K has an oxidation number of +1. In CO2, O has an oxidation number of -2, C has an oxidation number of +4. In K2CO3, O has an oxidation number of -2, C has an oxidation number of +4, and K has an oxidation number of +1. In the given reaction, the oxidation numbers for each atom remain the same as in their individual compounds.
O.S of K = +1 O.S. of Ta = +5 O.S. of F = -1
The oxidation number of potassium (K) is always +1 because it is an alkali metal in group 1 of the periodic table. The oxidation number of nitrogen (N) in compounds is typically -3. Therefore, in K3N, the oxidation number for K is +1, and for N, it is -3.
In K2MnF6, +1 for K, +4 for Mn and -1 for F In SbF5, +5 for Sb and -1 for F In KSbF6, +1 for K, +5 for Sb and -1 for F In MnF3, +3 for Mn and -1 for F In F2, 0 for F
Pottasium has +1 oxidation number.Iodine has -1 oxidation number.
