Well,
oxidation, or the redox reaction is in fact a very board family of reactions.
Electrons don´t just leave from or go to the outer space; they transfer. A
reaction that involve an oxidation, and any such reaction is a redox reaction.
The reactant that causes the reduction of something is called the reducing
agent. Sodium is the reducing agent in the reaction with chlorine. The reactant
that oxidizes something else is called an oxidising agent. Chlorine is the oxidizing
agent in the reaction with sodium. Na + Cl ----> Na+ + Cl-
So in fact we can have "oxidation" or a redox reaction without oxygen. Just
the reactant for the electron to "move" is needeed.
take care,

Steven,
So you're saying that we can have oxidation without oxygen?
Sounds like an oxymoron to me. :)

somewhere to go so something is going to gain electrons and that is the
reduction part. So to undergo oxidation, something has to be reduced -
usually it's oxygen that accepts the wayward electrons but it doesn't
always have to be so.
For example:
Ba + F2 -> BaF2 is an oxidation-reduction reaction that doesn't involve
oxygen. Here F is the oxydizing agent.
