How gold is formed? geologically, in the earth, and naturally. Gold is a precious metal that has been one of the important elements in human life since ancient times until now. Many uses of gold used by humans, for example, are used as dowries for computer components, so gold is sought after.
Gold is a chemical element of the periodic table that has the symbol at (Latin: 'aurum') and Atomic Number 79. A soft and ivalent trivalent, yellow, heavy, "forged", and "tenacious". Gold does not react with other chemicals but is hit by chlorine, fluorine, and aqua Regia. These metals are found in gold or powder nuggets on rocks and in alluvial deposits and one metal coin. The ISO code is XAU. Gold softens in liquid form at a temperature of about 1000 degrees Celsius.
Gold is a soft and easy forged metal, hardness ranges from 2.5 - 3 (MOHS scale), and its specificity depends on the type and content of other metals that combine them. Gold-carrying minerals are usually associated with minerals (gangue minerals). Minerals are generally quartz, carbonate, tourmaline, flourpar, and small amounts of non-metallic minerals. Gold-carrying minerals are also associated with oxidized sulfide deposits. Gold-carrying minerals consist of gold nativ, electrum, golden goldena, a number of alloys, and gold compounds with elements of sulfur, antimony, and selenium. Electrocution is actually a type of Nativ gold, only silver content in it> 20%..
Although widely used, elements that have an AU symbol in the chemical periodic table are actually rare on this earth.
Of course, we often ask about which gold? Does it come from the earth? So, how does gold form?
According to the educational website Ted-ed, gold on earth comes from outer space. Precisely the golds formed during the supernova, the phenomenon of stellar explosions in space.
At that time, the gold material was still in the form of gas and dust which was then combined into the planets. On Earth, gold is scattered in the bowels of the earth due to geothermal activity.
Only then after gold is mined and processed, the gold ore in the bowels of the earth can be the tool or jewelry that we usually see today.
The process of gold creation in supernovae

The elements try to be heavier elements like iron or nickel. However, when they try to become heavier elements, nuclear fusion usually has to run out of energy.
This causes the outer layer of the star to shrink to the core. It happens because there is additional sudden energy from the outer layer that causes the explosion that we know as a supernova.
In the nucleus of a Supernova, there is extreme gravitational pressure that makes protons and electrons forced to combine in essence to form neutrons.
Neutron itself is very easily captured by elements such as iron, which then makes the formation of more severe elements that cannot be created by stars. These elements are silver, gold, leading to uranium.
In Supernova, heavyweight elements are formed in seconds.

Actually, we can produce gold on earth. With the help of particle accelerators, the researchers were able to replicate the complex nuclear reactions that makeup gold in space.
But machines can only make gold by changing one atom at a time in an element. So it is estimated that making one gram of gold will take a very long time.
This makes it very inefficient and instead makes gold more expensive due to high production costs.
Looking for gold in space
If indeed, someday the gold in the bowels of the earth runs out, there are several other places that could be human alternatives in finding gold.
In the oceans, it is estimated that there are about 20 million tons of gold experienced, but the gold can be said to be in very small particle conditions.
That makes it difficult and expensive to process with technology now.
In addition, along with technological advances, there are other places where we can look for gold and other minerals, namely asteroids or other planets.
Before we get there, for now, we still have to be fought in the most economical traditional way to get gold, which is mined in the bowels of the earth.
