Why is gold so valuable?

We have all heard the story that in ancient times salt was so valuable that it was used as a means of payment, when humans began to trade, they used barter, that is, the exchange of one product for another, but a problem arose: 
What happens if you have something that I do not want or I have something that you do not want? ", Because of this, the idea of ​​using something that we all recognize as" useful "arose, and the salt began to be used.

Now, today, we all know that glod is valuable, but why? Why not another? We have 118 elements in the periodic table. The answer is incredible: BECAUSE YES.

Gold has no value on its own, we humans gave it arbitrarily, but WHY? 
For this you have to see the periodic table:

Our goal is to find a material:

• Easy to transport (not like uranium)
• Easy to measure, to divide, to stack (not like water, I never heard someone say "I have 3 waters")
• Stable, do not react to contact anything (such as chlorine with sodium)
• That it does not deteriorate (like iron, which oxidizes)
• Make it easy to measure (not like wood, because the tree depends, the density is different)

Then we remove the liquid elements because it is difficult to make coins with this.

Some are directly POISON like mercury or bromine, I do not think much of the idea of ​​carrying them in your pocket.

We must also discard plutonium, uranium or thorium, since they are unstable, radioactive and basically we would die when approaching.

So we would continue with the gases, metals that are oxidized and a long etcetera. If we see a periodic table we will see that both the elements of the left and right are not useful, so we have to ask ourselves: And the middle?

To extract titanium and zirconium you need at least 1000º Celsius. Iron, aluminum or copper are oxidized with water and air, are short-lived. The water and air is no small thing, more than 30 more elements are oxidized by this, making the list is drained a lot.

There are some, like the famous platinum, but unfortunately it takes more than a thousand kilograms of ore to extract an ounce (28.7 grams) and we also need very high temperatures to extract it.

We are left then:  silver and gold . Both are scarce (but not so much), stable (although silver has a problem that I already explain later) and are easy to manipulate to create coins or ingots. 
Both are good, not for nothing both were used for thousands of years, I say, in ancient Rome and in different empires copper or others were tried, but only silver and gold stood the test of time.

However, silver, if it is not maintained in ideal conditions (something that never happens if we consider that being a means of value people will take them from one place to another) will also fade with the passage of time with the contact with the air.

And finally, the champion: gold.  It is very crazy, because it is chemically the "least interesting" (it is an expression) and it is precisely this that makes it particularly precious.

It has no value per se (by itself), we gave it to ourselves. It is stable, malleable, duc

tile, portable, it is not poisonous, it does not shine in the dark. It is perfect.

So you know, gold is not worth anything, so if you want to give me a little talk to me privately and I pass my address, greetings.
