Interesting Facts About The Element Gold
Almost everyone loves gold, but many do not know much about the shiny element. Here are a few interesting facts on the element, gold. Gold happens to be the element that is yellow in color. Though other elements may gain a yellowish color, it is due to oxidation or chemical reactions.
Almost all of the gold that is on the planet came here over 200 years ago from meteorites.
Gold’s element symbol is AU. The name for the symbol comes from the Latin word gold, aurum. Aurum translates to “glow of sunshine.”
Interesting Facts About Gold
Another interesting fact about gold is how ductile it is. One ounce of the precious metal can be flattened and stretched 5 miles long.
When it comes to malleability, or how easy it is to hammer metal into thin sheets, gold is number one. One ounce of gold can be beaten down to a 300 square feet sheet. It can even become transparent. Some reason why the thin sheets of gold appear to be a greenish blue in color is that the element reflects red and yellow, strongly.
Gold is also non-toxic. Some restaurants add gold metal flakes to their fancier dishes or drinks.
24 karat gold is pure gold. 18 karat is only 75%, 14k is 58.5%, and 10k is 41.7% gold. Though typically, the remainder is silver, it can be either platinum, palladium, zinc, or even copper.
Gold does not easily corrode. Air, water, and acidic conditions leave gold unreactive. Though acids do dissolve metals, for gold to dissolve, one will have to use aqua regia.
Gold is good for other things such as electronics, electrical wiring, and dentistry. Also in medicine, coloring glass, and shielding radiation. Metallic gold that is high in purity tends to be tasteless and odorless. It makes sense especially with the metal be unreactive. It is metals ions that that makes it, so that metallic compounds and elements have flavor or odor.
