FAQs
How do you find the oxidation number? The oxidation number of an element in a compound can be determined by several rules and guidelines. Some common rules include:
- The oxidation number of an element in its pure elemental form is always zero.
- In most compounds, oxygen has an oxidation number of -2, unless it is in a peroxide where it is -1.
- Hydrogen typically has an oxidation number of +1, except when it is bonded to a metal where it is -1.
- The sum of oxidation numbers in a neutral compound is zero, while in an ion, it equals the charge of the ion.
