Sulfur is a abundant non metal that makes up 3% of the earth’s mass. It was discovered by Antoine Lavoisier in 1789 but in 1823 by the German Chemist Eilhard Mitscherlich obtained Sulfur crystals from cooling molten sulfur. Sulfur exists as allotropes (similar formulas but different structures) of a rhombic and monoclinic Sulphur crystals. Sulfur however has been known since ancient times due to its elemental presence in volcanoes. Sulfur is used in the vulcanisation of rubber and in the production of gunpowder, its most important use is in the production of Sulphuric acid in the contact process. Whilst Sulfur does not smell itself the compounds that it creates such as Hydrogen Sulfide produces a smell similar to that of rotten eggs. It is located in Group 16 as a non metal yellow solid at room temperature, it is brittle. It has a melting point of 115°c and a boiling point of 444°c.
