Oxidization -

"Oxidative stress" occurs when unstable molecules called free radicals damage cells. This is why diets rich in antioxidants —substances that inhibit oxidation—are considered healthy.

It is important to note that oxidation never happens in isolation. It is always paired with , which is the gain of electrons. Together, these are known as redox reactions . You can remember this using the mnemonic OIL RIG : O xidation I s L oss (of electrons) R eduction I s G ain (of electrons) Common Examples of Oxidation oxidization

When iron is exposed to moisture and oxygen, it undergoes oxidation to form iron oxide, or rust. The iron atoms lose electrons to oxygen atoms. oxidization
