                                                 Gold Element

Gold is the 79th element on the periodic table of the elements. Its atomic symbol is ‘Au’ that came from the old Latin name for gold, ‘Aurum’ that means ‘shining dawn’. Gold is the only metal that naturally has a shiny yellow color. It is the most malleable element.

This metal is also included in noble metals as it is chemically unreactive and does not degrade by air, moisture or acidic conditions.
