However, we shall see that although "normal matter" is composed of atoms and molecules, most of the matter in the Universe is not in the form of atoms or molecules, but rather in the form of a plasma. We discuss plasmas in the ... Atoms are composed of three classes of constituents, as illustrated in the following table.

Atoms are composed of little balls ... This is a material which has been pumped into an upper energy state such that there are more molecules (or atoms or electrons as the case may be) in a upper state than in an immediately lower state. The molecules coming down to the lower state give off energy in the form of photons,
