Is Gold Made on Earth?
On Earth, gold is found in ores in rock formed from the Precambrian time onward.
It most often occurs as a native metal, typically in a metal solid solution with silver (i.e.
as a gold silver alloy).
Such alloys usually have a silver content of 8–10%.
Electrum is elemental gold with more than 20% silver..

Will gold ever lose its value?
Although the price of gold can be volatile in the short term, it has always maintained its value over the long term. Through the years, it has served as a hedge against inflation and the erosion of major currencies, and thus is an investment well worth considering.
What is the rarest metal in the world?
franciumThe rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
What will gold be worth in 5 years?
Some industry experts are predicting that gold could be worth anywhere from $3,000–$5,000 per ounce in the next 5–10 years! For those who think gold prices will increase, they cite that people are now recognizing the value of gold, which will increase the demand, therefore increasing the value.
Where is gold most commonly found?
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.
Where did all the gold on Earth come from?

Gold sometimes moves opposite to the U.S. dollar because the metal is dollar-denominated, making it a hedge against inflation.
Why is gold so unreactive?
Gold is unreactive because the nucleus of the gold is heavy such that the electrons must travel at the speed of light. The 6s electrons in the gold are less accessible for bonding and their energy is dissimilar to many reactants. This gold makes unreactive.
