Gold properties Gold is dense, soft, shiny, malleable and ductile Melting point is 1064,18°C Atomic mass 196,9655g/mol and atomic number 79 In addition gold is very dense a cubic meter weighing 19 300kg High corrosion resistance and good electrical conductivity

History of gold Gold has been a valuable and highly sought-after precious metal Coinage, jewelry and other arts since long before the beginning of recorded history (6 000 B.C)

History of gold Has been used monetary policies Were widely supplanted by fiat currency starting in the 1930s. Gold certificate and gold coin currencies were issuea in the U.S in 1932
