ANSWER:Step 1 of 12
Oxidation number is defined as the charge that an atom has or appears to have when electrons are distributed according to certain rules.
Rules to assign the oxidation number;
* The oxidation number of the atoms in any free uncombined element is zero.
* The sum of the oxidation numbers of all atoms in a compound is zero.
* The sum of the oxidation numbers of all atoms in an ion is equal to the charge of the ion.
* The oxidation number of fluorine in all its compounds is -1.
* The oxidation number of other halogen in their compounds is usually -1.
