Sulfur

Major physical properties Classification: Non-metal Melting point: 112.8 C Boiling point: 444.6 C Colour: Yellow coloured lumps, crystals, powder, or formed shape Odour: Odourless, or faint odour of rotten eggs if not 100% pure

Major chemical properties Sulfur reacts when mixed with saltpetre and charcoal (reaction of gunpowder) The on the next slide shows the result from burning a mixture of zinc metal powder and sulphur.

The discovery of Sulfur The discoverer of Sulfur is unknown; however it has been documented that Sulfur has been used since ancient times. Sulfur is obtained naturally salt domes" along the Gulf Coast of the USA.

Current uses Sulfur is used in Epsom salts, gunpowder, some medicines and matches.

Interesting facts Sulphur is found in meteorites, volcanoes and hot springs Jupiter's moon Io owes its colours to various forms of sulphur. It is a reactive element that given favourable circumstances combines with all other elements. It’s a non-metal, belonging to the Chalcogen group
