Can Chemistry Be Reduced to Physics?

Physicalists think that all facts of the universe may be explained in terms of physical realities. In other words, a physicalist has (to know) and be able (how) to put all various kinds of equivalent approaches in the scope of reductionism. Reductionists claim for an extensive spectrum of ontological and epistemological ideas. In the field of reductionism, reduction of chemistry into physics is mostly spoken of. Reductionist physicalists claim that they are able, by employing relativistic and non-relativistic quantum mechanics, to calculate energies of atoms. In the present article, the author has tried to provide an overview of reductionism and its patterns and versions, and thus to show weakness of this claim in the field of reduction of chemistry into physics.
