oxidation numbers

Is the oxidation number just the charge? If not, how do you find the oxidation number?

[Kassidy Ford 1I]

There are several molecules with known oxidation numbers, for example O is known to have an oxidation number of -2. Using the known oxidation numbers you can solve for oxidation numbers of other molecules, for example if you have the molecule MnO4 with an overall charge of -1, then you know that Mn would have an oxidation number of +7 so that the overall molecule has a charge of -1.

[Maya Beal Dis 1D]

The charge of a molecule is always equal to the sum of the oxidation numbers multiplied by the amount of each element, so you can use the net charge to determine oxidation numbers.

[Amir Bayat]

The net charge is the oxidation number of the element multiplied by the amount of that element available. Therefore the oxidation number is not necessarily the charge, but it can be utilized to find the charge.

You use the known oxidation numbers for some elements and fill in the rest. The sum of all the oxidation numbers should add up to the total charge of the molecule.

[Edmund Zhi 2B]

Use common oxidations states such as that of very electronegative atoms like oxygen, nitrogen, and fluorine, and then fill in the rest to make sure that the charges add up to the overall charge of the molecule

Here is a website with some common rules that one should follow when assigning oxidation numbers: https://www.thoughtco.com/rules-for-assigning-oxidation-numbers-607567.

you can usually use commonly known oxidation numbers to solve for the remaining unknown oxidation numbers.

[Anna Heckler 2C]

The oxidation number of simple ions is equal to the charge of the ion. When calculating oxidation numbers, we can use known oxidation numbers to find the unknowns.
