what is oxidation and reduction plz help me this question ?

Answer:
oxidation mai charge ka increment hota hai and reduction mai charge ka decrement hota hai kise bhi reaction mai
Answer:
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
REDUCTION involves a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. The other half of the reaction involves oxidation, in which electrons are lost. Together, reduction and oxidation form redox reactions (reduction-oxidation = redox). Reduction may be considered the opposite process of oxidation.
The H+ ions, with an oxidation number of +1, are reduced to H2, with an oxidation number of 0, in the reaction:
Zn(s) + 2H+(aq) → Zn2+(aq) + H2(g)
Another simple example is the reaction between copper oxide and magnesium to yield copper and magnesium oxide:
CuO + Mg → Cu + MgO
