I dont know what you mean by s,l,g  but dark matter is definitely not composed of normal atoms.  It is believed to consist of particles that interact only by gravity and not by the strong weak or electromagnetic forces.  It has always seemed quite reasonable to me that therte should be some particles like this in the universe after al there are other particles that only react to some of the forces.

Solids, liquids and gases are composed of atoms. Atoms are held together by forces that do not affect dark matter. Therefore dark matter cannot form atoms.
