For most elements, their highest attainable oxidation number is equal to the number of valence electrons. Examples are the maximum oxidation numbers for: sulfur is +6, phosphorus is +5 and chlorine is +7. Fluorine is an exception which bears oxidation numbers 0, -1/2 and -1.
To find the highest oxidation number for an element, look at its group number on the Periodic Table. Elements in groups 1 and 2 typically exhibit the highest oxidation numbers of +1 and +2, respectively. For transition metals, the highest oxidation number can be determined by considering the number of valence electrons and the common oxidation states observed for that element.

In which compound does chlorine have the highest oxidation number?
Chlorine has its highest oxidation number of +7 in perchloric acid (HClO4).
What is the formula for iron using the highest oxidation number?
The formula for iron using the highest oxidation number is Fe2O3, which is iron(III) oxide. In this compound, iron is in the +3 oxidation state.
What is the highest oxidation number for carbon?
The highest oxidation number for carbon is +4, which is found in compounds such as carbon tetrachloride (CCl4) and carbon dioxide (CO2).
How you can find the oxidation number for Ni?
To find the oxidation number for Ni (nickel), you look at the overall charge of the compound or ion it is a part of. For example, in NiCl2, each Cl has an oxidation number of -1, so the sum of the oxidation numbers must equal the overall charge of the compound. Therefore, as NiCl2 is neutral, the oxidation number of Ni must be +2.

How you find the oxidation number?
For a neutral atom or compound, the oxidation number is always 0. For an ion, the overall oxidation number is its charge. If you need to find an oxidation number to a particular atom of a compound, there are two ways: working out the Lewis structures or balancing the charges.
What is the oxidation number for Ag3PO4?
The oxidation number of silver (Ag) is +1 and the oxidation number of oxygen (O) is -2. To find the oxidation number of phosphorus (P) in Ag3PO4, we can set up an equation: 3(+1) + x + 4(-2) = 0. Solving for x, we find that the oxidation number of phosphorus in Ag3PO4 is +5.
How do you find the oxidation number for chlorine?
To find the oxidation number of chlorine, consider that chlorine typically has an oxidation number of -1 in its compounds. However, in certain situations, such as when bonded with oxygen or other halogens, chlorine can have different oxidation states. It's important to follow the usual oxidation number rules and balance the charges in the compound to determine the oxidation number of chlorine.
How do you find oxidation number of Cu in CuO?
To find the oxidation number of copper (Cu) in CuO, consider that oxygen (O) usually has an oxidation number of -2. Since CuO is a neutral compound, the oxidation number of Cu can be calculated by setting up an equation where the sum of the oxidation numbers equals zero. In this case, the oxidation number of Cu in CuO is +2.
What is the oxidation number of Mg2Si2O6?
The oxidation number of Mg is +2. The oxidation number of O is -2, and since there are 6 oxygen atoms in Mg2Si2O6, the total oxidation number contributed by O is -12. The oxidation number of Si is +4. Therefore, to find the oxidation number of Mg in Mg2Si2O6, you can set up an equation as follows: 2x + 2(+4) + 6(-2) = 0, where x is the oxidation number of Mg. By solving this equation, you find that the oxidation number of Mg is +2 in Mg2Si2O6.
What is the oxidation number of Na2CrO4?
The oxidation number of Na in Na2CrO4 is +1 and the oxidation number of O in Na2CrO4 is -2. To find the oxidation number of Cr, we let x be the oxidation number: 2(+1) + x + 4(-2) = 0 x = +6 Therefore, the oxidation number of Cr in Na2CrO4 is +6.
