Normally, Sulfur is found in the solid state with a brilliant yellow color. It smells like safety matches. It is a soft substance, but does not dissolve in water. However, it is completely soluble in Carbon disulfide, and is slightly soluble in some organic solvents like Benzene and Toluene. When it burns in air, it gives a blue flame, and forms Sulfur dioxide gas. Sulfur reacts with most elements to form a stable compound. It however, does not react with the noble gases.
