What chemical property is present in substances that react slowly to oxygen?

If the substance reacts with oxygen, it may have a low number of electrons in its valence band, which are attracted to the highly electronegative oxygen atom. The process may involve stripping of electrons from the substance, which is the essence of oxidation.
