Is chlorine a pure substance

In the periodic table, however, the mass of a chlorine atom is given as 35.45 u. This results from the relative abundance of 75.76% of chlorine-35 and 24.24% of chlorine-37. A similar method is followed in case of molecules and the mass of a molecule relative to that of C-12 is called the Relative Molecular Mass (RMM). Pure and Mixed Gases. Pure gases can take several different forms. They might be made up of individual atoms, such as neon, atomic gases or noble gases. Oxygen is also a pure gas because it is made of one type of item; however, it is an elemental molecule. Pure gases may also be compound molecules, which are comprised of a bunch of different atoms.
