Gold | Geoscience Australia

Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold. This is referred to as 'native gold'.

Can We Turn Lead Into Gold? From Alchemy to Nuclear Physics

As we mentioned briefly in another post, 100 fun chemistry facts, the hallmark goal of alchemy, turning lead into gold, is actually possible.
