The definition of oxidation state is as follows: Oxidation state is a number given to the atom of an element when participating in a chemical reaction.
OXIDATION STATE:
- The atoms of elements are not always neutral i.e. carry no charge. They sometimes carry either positive or negative charges to become ions.
- Ions can either be cations (positively charged) or anions (negatively charged). The amount of charges are represented by numbers placed as a superscript in front of the element involved.
- These superscript charge assigned to a corresponding element during a chemical reaction is called oxidation state. The oxidation state of an element portrays the number of electrons gained or lost during the reaction.
Therefore, oxidation state can be defined as a number given to the atom of an element when participating in a chemical reaction.
