Why is gold needed?

Answer 1

It's not really needed for anything besides jewelry, although astronauts did have a very thin layer of gold on their helmet faceplates. Gold is a non-reactive metal that is the by-product of ancient stellar death cycles. All gold that exists in the earth's crust fell to earth from space. Deep within the earth is likely a lot more gold, since it is so dense.

Best Answer - Chosen by VotersThere are other metals like platinum, rhodium etc that do not corrode or rust as well as gold, and they are also not attacked by acids except in aqua regia, Mercury and cyanide. So gold is not unique in that respect.

Gold's unique property that depends on it's atomic structure is it's malleability. That means that is the ONLY metal that can be hammered out into incredibly thin sheets. This gives us the gold foil lettering on books, the ultra thin coating given to statues, like the Buddhas in Thailand, guilding on frames plus countless electronic applications(where an ultra thin layer of gold is electroplated).

Ultra thin gold foil is commonly called gold leaf. Gold leaf is gold that has been hammered into extremely thin sheets and is often used for gilding. Gold leaf is available in a wide variety of karats and shades. 22-karat yellow gold is the most commonly used.

Layering gold leaf over a surface is called gold leafing or gilding. Traditional water gilding is the most difficult and highly regarded form of gold leafing. It has remained virtually unchanged for hundreds of years and is still done by hand.
