It is a concept related to the ability of atoms of various substances to lose or gain electrons

Substances that have the ability to oxidize other substances are said to be oxidative and are known as oxidizing agents, oxidants or oxidizers.

An oxidant removes electrons from another substance.

Similarly, substances that have the ability to reduce other substances are said to be reductive and are known as reducing agents, reductants, or reducers.

A reductant transfers electrons to another substance, and is thus oxidized itself.

And because it "donates" electrons it is also called an electron donor.

It is a transfer of electrons but they call it Oxidizes! Is there no Oxygen involved with Oxidization?

Oxidation and reduction properly refer to a change in oxidation number—the actual transfer of electrons may never occur.

What changes then?

Thus, oxidation is better defined as an increase in oxidation number, and reduction as a decrease in oxidation number.
