Now the matter is considered as formed from atoms.
Most matter doesn't exist as individual atoms. Inert or "noble" gasses like helium and argon excepted, most matter exists in molecules that are composed of two or more atoms. Even pure oxygen isn't individual atoms; oxygen is the O2 molecule composed of TWO oxygen atoms. Except within the cores of stars, hydrogen, the most common element, normally exists as the H2 hydrogen molecule. So in general, matter is composed of molecules, which are composed of atoms.
