oxidation number of Iodine in IF4
F is -ve and I is +ve
therefore,
x-4=+1
x=5
The oxidation number of NO3- is -1. Each oxygen atom typically has an oxidation number of -2, totaling -6 for the three oxygen atoms. Since the overall charge of the nitrate ion is -1, the nitrogen atom must have an oxidation number of +5 to balance the charge.
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
Silver has plus one.Chlorine has minus one.
In PH₄⁺, the oxidation number of phosphorus (P) is +1 since hydrogen (H) typically has an oxidation number of +1 in compounds. Each hydrogen atom in PH₄⁺ contributes a +1 charge, so the total charge of the cation is +1.
The oxidation number of hydrogen in InH3 is +1. In compounds, hydrogen usually has an oxidation number of +1, as it has a tendency to lose its single electron to form a positive charge.

SO2 is neutral. Please refer to the oxidation states. Since all oxidation numbers added together in a compound must equal zero. Which means that : S+(-2*2)=0, so S has an oxidation number as +4, in which O2 has an oxidation number of -2*2 = -4. Just find out the oxidation number of the compounds each time through equation and you'll know the charge. Easy.

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.
manganese is a 3d element. +2 is the oxidation number in this ion.
Think about it, the overall charge of CaH2 is neutral (meaning a charge of 0). One of the oxidation rules states that H has a charge of -1 if it is apart of a hydride (Ex LiH, CaH2 is also a hydride). Because there are 2 Hs, it's charge would be -2. If you add the charge of calcium which is 2 with the hydrogens charge -2 you would get 0, which is right because the molecule is neutral. 1- Apex
The name given to the electrical charge on an ion is a oxidation number. The charge of the ion typically formed by strontium is 2 plus.
In the compound Fe2O3, the iron atoms have an oxidation number of +3. This is because oxygen typically has an oxidation number of -2, so since there are three oxygen atoms in Fe2O3, the total negative charge from the oxygen atoms is -6. The two iron atoms must have a total charge of +6 to balance this, resulting in an oxidation number of +3 for each iron atom.
The oxidation number of Cr in Cr3+ is +3. This is because each Cl ion has a charge of -1, and since the compound is neutral, the total positive charge from Cr must equal the total negative charge from the Cl ions.
