Oxidation is found by putting the unknown oxidation number as x and all other values of oxidation number are added, and are put equal to the total charge on the species. Any constiuents ion's oxidation number can be put equal to the charge. Oxygen always show -2 oxidation state except peroxide, AND superoxides, an other exception is also there i.e. OF2. Alkali metals always show +1 oxd state. Eartheline earth metal show +2 oxd state. Eg- In KMnO4, +1 for K, x for Mn, all O's with -2 each Thus, (+1) + (x) + (4*-2) = 0, 0 for KMnO4 is a neutral species. Here, x = +7. Oxd state or number of Mn in KMnO4 is 7.

There are two oxidation numbers. P shows +5 oxidation number.
What is THE common oxidation number for tantalum?
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
Can metals have positive and negative oxidation numbers?
No, they can't only have positive oxidation numbers in compounds.
What do you use oxidation numbers and their least common multiples to write?
They are used to write balanced chemical equations.

Does oxidation numbers take into account stoicheometery?
The simple answer is not always. The stoicheometry deals with oxidation numbers only in redox reactions. The ratio of the change in oxidation numbers is straightly its stoicheometry.
What is the oxidation number of ZnCl?
The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. Cl has an oxidation number of -1. Therefore, Zn must have an oxidation number of +1.
What are the oxidation numbers of the elements fe2o3?
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
Why must oxidation numbers be assigned to the elements before writing a chemical formula?
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
