Where did all the gold come from?

During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals — such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.

How did gold get its name on the periodic table?

Gold gets its English name from the Germanic word gulþa (meaning gold). The Old English word geolu means yellow. In Latin, gold was called aurum. That is why the chemical symbol for gold is Au.

Pure gold is soft and is usually alloyed with other metals, such as silver, copper, platinum or palladium, to increase its strength. Gold alloys are used to make jewelry, decorative items, dental fillings and coins. The amount of gold in an alloy is measured with a unit called a karat.
