Definition

1. Adjective:
   • Having undergone a chemical reaction with oxygen, resulting in a loss of electrons or an increase in oxidation state. This process often involves the addition of oxygen atoms or the removal of hydrogen atoms from a substance.

Usage

The adjective oxidized is used to describe a substance that has been altered by oxidation. It is commonly used in chemistry, materials science, geology, and everyday contexts (e.g., describing tarnished metal). * It typically follows a linking verb like is, was, becomes, or appears (e.g., "The metal is oxidized"). * It can also come before a noun (e.g., "oxidized cholesterol").
