Get started for freeSulfur is known in many forms, including yellow sulfur (formula \(\mathrm{S}_{8}\) ) and orange-red sulfur (formula \(\mathrm{S}_{6}\) ). Heating either of these forms to very high temperatures can yield \(\mathrm{S}_{2}\). Also known is a substance with the formula \(\mathrm{SO}_{2}\). Since all of these substances are made of elements, are they all elemental substances? Explain.
