What are 5 characteristics of sulfur?
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
What is the discovery background of sulfur?
It was known from prehistoric times and thought to contain hydrogen and oxygen. In 1809, the French chemists Louis-Joseph Gay-Lussac and Louis-Jacques Thenard proved the elemental nature of sulfur. Sulfur, the tenth most abundant element in the universe, has been known since ancient times.
What does sulfur look like?
Elemental sulfur is a pale yellow colour. At room temperature, it is a soft powder that crumbles when touched. Elemental sulfur does not have a smell when it is on its own, but when it forms a compound – with hydrogen, for example – it can stink!
