Not sure what L(s) is supposed to be, but regardless, the oxidation state of Na changes from 1+ in NaOH to zero in Na(s).
It does not change for @pex
It goes from +1 to 0.
it goes from 0 to +1
It goes from +1 to 0
These are not mutually exclusive. A reaction can be oxidation and exothermic. Oxidation reactions involve a change in oxidation state (charge) which is interpreted as a loss of electrons. Exothermic reactions release heat energy.

This is an oxidation reaction.
All oxidation is a chemical reaction.

It is an example of chemical change which cannot be reversed. In this change, Iron oxidizes under the presence of oxygen and moisture. The reaction is called a reduction-oxidation, or redox, reaction.
Yummy, Chemistry :) Redox reactions - Oxidation reaction This is a reaction in which atoms have undergone a change in their oxidation state.
Oxidation is a chemical reaction; but a physical modification can also occur.
if oxidation states change, it is a redox reaction
Burning is an oxidation reaction.
