Gold was one of the first metals to attract attention in human history – and for a good reason. Gold is visually pleasing, malleable, and easy to work with. There are examples of elaborate gold workmanship dating back thousands of years from ancient Egyptian and Assyrian artisans. Here are three fun facts about gold:
Gold is the only yellow metal
One of the fun facts about gold is that it’s only metal that’s naturally yellow or “golden.” Other metals can develop a yellowish color, but only after they’ve oxidized or reacted with different colors. So why is this? It has to do with gold’s atomic structure.
The technical reason why gold is yellow has to do with many chemistry concepts that would require a college-level lecture. But to put it simply, gold’s color comes from the electromagnetic radiation the human eye sees and what gold reflects back.
Gold comes from space!
The idea that all the earth’s gold came from outer space may sound like something from a science fiction film, but it’s true.
A study from the University of Bristol concluded in 2011 that the earth’s store of precious metals – including gold – derives from a burst of meteorite impacts around 3.9 billion years ago.
Researchers determined when the meteorite impacts occurred by measuring isotopes in rocks that are nearly four billion years old in Greenland. The scientists call the meteorite impacts the “terminal bombardment.”
Gold has several unexpected uses
Some people may think gold is only used in jewelry or coins. But there are many different uses for gold – so many, in fact, that experts say gold is the most useful mineral mined from the earth.
The primary use of gold is in jewelry. About 78% of gold consumed globally each year is used in jewelry manufacture. Most people also know that gold has long been used for financial purposes, such as in money and bullion.
But did you know gold is also used in electronics, medical devices, dentistry, aerospace, and glassmaking? For example, gold parts are used in cell phones as highly efficient conductors to carry tiny currents and low voltages.
