In chemistry, gold is chemical element 79, a transition metal in Group 11. It has an atomic weight of 199.96 a.m.u. Its symbol is Au, from the Latin word for gold, aurum.
Gold is very malleable, which means it can be hammered into thin sheets; and ductile, which means it can be pulled into wire. When it is used in money or in jewelry, it is often mixed with silver or some other metal to make it harder.
Most metals are gray in color. Gold's yellow color comes from the way that electrons behave in it.
There have been many discoveries of gold in Australia. The most important discovery of gold was probably discovered by Sir Edward Hargraves. Sir Edward Hargraves started the first Australian gold rush.
