Hi...

Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.

Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.
An example of a reaction is that between hydrogen and fluorine gas to form hydrofluoric acid:
H2 + F2 → 2 HF
In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions.
H2 → 2 H+ + 2 e-
F2 + 2 e- → 2 F-
Note there is no oxygen anywhere in this reaction!

hope it helps you..

a substance is said to be oxidised -
1oxygen is added in rhat substance.
2 hydrogen is removed in that substance.
3it will loose electrons.
reduction -
1hydrogen added in that substance.
2 oxygen is removed
3 it will gain electrons.
