12 characteristics of gold

 

Here are 12 of the most amazing features of gold:

· Gold is created by supernovae - explosions propelling cosmic elements that come together to form, among other things, planets.

· The presence of gold near the surface of the Earth is due to meteor showers that arose after our planet was formed,

· All of the gold ever mined would fit in a cube of 20 cubic meters.

· Today, it is not uncommon to extract 10 tons of rock or more to get an ounce of gold.

· Gold is extraordinarily dense - one cubic meter of gold weighs over 19 tons, which makes gold a metal almost twice as heavy as lead.

· Gold is malleable and extensible - an ounce of pure gold can be transformed into a thin sheet of gold nine square meters, or form a wire 80 kilometers long.

· Much of the gold present in the Earth's surface is buried too deep to be extracted,

· The presence in the earth's crust is 0.004 particle per million.

· The oceans of our planet contain up to 15,000 tons of gold.

· Since the origins of mankind, 172,000 tons of gold were extracted only

· Gold is malleable and extensible - an ounce of pure gold can be transformed into a thin sheet of gold nine square meters, or form a wire 80 kilometers long.

· Nanoparticles of gold thousand times smaller than the diameter of a human hair, are used in the field of medicine.

A human body contains an average of 7 milligrams of gold.
