- Oxidation numbers
- How to assign oxidation numbers
- Uncombined elements have an oxidation number of 0
- In compound ions, the overall oxidation number is equal to the charge on the ion
- The oxidation of a monatomic ion is the same as its charge
- The sum of oxidation numbers for a neutral compound is 0
- Combined oxygen is almost always -2, but there are exceptions
- In peroxides = -1
- In fluorides = +2 or +1
- Combined hydrogen is +1, except in metal hydrides it is -1
- How to assign oxidation numbers

- A loss of electrons
- Oxidation will increase
- Reduction
- A gain of electrons
- Oxidation number will decrease
- The transference of electrons
