What is it used for? Gold has always been used as an indicator of wealth and the fabulous death mask of Tutankhamun is a well known example. The Ancient Egyptians also believed that gold had a magical potency containing significant religious properties and was therefore referred to as the 'Flesh of the Gods'. Other uses of this precious metal include: Currency Coinage Jewelry Tableware Medicine and Health Care Dental alloys Electronics | Bohr ModelNumber of Protons: 79 Number of Neutrons: 118 Number of Electrons: 79 Number of Valence Electrons: 11 | Original Form Gold is a chemical element with the symbol Au and atomic number 79. It is a bright yellow dense, soft, malleable and ductile metal. The properties remain when exposed to air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. Less commonly, it occurs in minerals as gold compounds, such as with tellurium as calaverite, sylvanite, or krennerite. |
