Gold atoms in a crystal

GOLD: atoms of gold (Au) in a metallic crystal. Gold is a precious metal whose atoms are arranged in closely packed hexagonal layers. First and fourth layers are in line with each other. This gives what is known as a face centred cubic (FCC) pattern or cubic close packing (CCP). Gold is very unreactive.

Gold has been used as a medium of exchange (currency) and for medals for hundreds of years (e.g. gold doubloons, gold sovereigns). It used to underpin currencies (gold standard) and is still regarded as a safe haven for investors during turbulent financial times.

This animation is ideal for TV news items discussing the gold price or stock market, since the crystal is reminiscent of a gold ingot. Also suitable for businesses that deal in gold such as jewellers.
