Oxidization

is a fundamental chemical process defined by the loss of electrons by an atom, molecule, or ion during a reaction. While the name originally referred specifically to reactions involving oxygen, modern chemistry uses a much broader definition that encompasses any reaction where the "oxidation state" of a substance increases.

The substance that loses electrons. It causes the other substance to be reduced (by "donating" electrons to it). Why It Matters Understanding oxidation is critical for several fields: oxidization

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 is a fundamental chemical process defined by the

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. It causes the other substance to be reduced

Preventing the oxidation of metals (rust) saves billions of dollars in infrastructure costs annually.

"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.

Oxidation is everywhere, from the engine in your car to the cells in your body. Here are a few ways it manifests:
