Hello friends of steemit, time without publishing a content related to my professional area, well today I want to make reference to one of the most important minerals that the science of geology has, I am talking about "THE YELLOW GOLD", which is very useful in all over the world, gold is a chemical element that is located in the periodic table represented by the atomic number 79, this mineral belongs to the group number 11 of the periodic table, it is considered that gold is a soft transition metal, bright Yellow, this mineral is commonly used for the manufacture of coins, now someone knows that there is something around the world called the gold rush? , if friends constantly in all the mines of the world there is the largest gold exploitation in the history of gold considered the most precious mineral of all the chemical elements besides, for its great monetary value in the market, all the people want to have gold.

In this post, reference is made to the basic elements of this mineral and also to the atomic structure that defines this precious metal.

What do we call yellow gold?

Yellow gold is one of the most appreciated substances by our society, meaning wealth and victory. And why is it so sought after? Of all the metals in the universe, why has gold become so valuable? Well, it has been an accumulation of events that have led gold to be so highly valued; On the one hand, it is not the rarest metal, but it is quite difficult to get it. But there are some elements that are millions of times more rare. And, particularly, gold is not too interesting: it does not react with other elements. So, what is your virtue? Precisely his boredom, which makes him very valid as a currency.

Chemical qualities of yellow gold

Gold is a chemical element so it can only be found, not manufactured. It is inert, which means that: it is practically immune to deterioration, it is not very useful in any industrial or chemical process that uses it and is cheap to store for long periods of time.

It is notable for its rarity, density and excellent electrical conductivity.

Gold has a lot of industrial uses thanks to its physical qualities. It is used in the dental industry and in the manufacture of some electronic products that need high-quality, non-corrosive contacts.

However, its really practical uses are numerically insignificant. Of all the gold mined from the earth, most of it is used in these three ways:

• As a personal adornment, where its color and its relationship with wealth contribute to its use in the manufacture of jewelry. (Around 60% of the global supply).
• As a public refuge of wealth, by supporting the monetary systems. (Around 20% of the global supply).
• As a refuge for private wealth (Around 15% of the global supply).

Abundance of yellow gold

Gold is extremely rare. According to geological experience, it is almost always found in low concentrations in rocks.

Gold nuggets are an exception, but they are responsible for a tiny part of the gold discovered. Interestingly, there is gold in the sea water, but although the aggregate amount is large (because the oceans are immense), the concentration is low and its extraction is above any technology. The cost of pumping 1,000 tons of seawater to process it far exceeds the value of any amount of gold that would be extracted.

The average concentration of gold in the earth's crust is 0.005 parts per million. The extraction technology is expensive mainly because the process always requires the manipulation of large physical quantities of ore to obtain very small results. It takes a large amount of energy necessary for the process and sometimes does not compensate for the quality of ore that can be worked profitably. The increase in energy costs always has an impact on mining viability.

Atomic properties of yellow gold

The transition metals, also called transition elements, is the group to which the gold belongs. In this group of chemical elements to which the gold belongs, are those located in the central part of the periodic table, specifically in block d. Among the characteristics of gold, as well as those of other metals, is that of including in its electronic configuration the orbital d, partially filled with electrons. Properties of this type of metals, among which gold is its high hardness, having high boiling and melting points and being good conductors of electricity and heat.

The state of gold in its natural form is solid. Gold is a chemical element with a metallic yellow appearance and belongs to the group of transition metals. The atomic number of gold is 79. The chemical symbol of gold is Au. The melting point of gold is 1337.33 degrees Kelvin or 1065.18 degrees Celsius or degrees centigrade. The boiling point of gold is 3129 degrees Kelvin or 2856.85 degrees Celsius or degrees Celsius.

Use and importance of yellow gold

In addition to being used as an economic reserve for countries and as jewelry for the vanity of man, gold has some other important uses in industry and science.

• Do not forget that it is the best conductor of all the metals of electricity and heat ... it is used in electronic components and in computer chips precisely because of this property.

• In some high performance cars like the most powerful ferrari and lamborghini, gold is used in engines as a heat dissipater, since no other material does it with such good efficiency as gold.

• It is also used as a chemical reagent in some gold salts.

• In genetic engineering small gold pellets are used to introduce genes into the cells ... this metal is suitable because it is totally inert.

Conclusion.

As a final analysis can be summarized that gold is a chemical element of great importance for the daily life of society because this precious metal is widely used for purposes of monetary benefits mainly in addition to being used in other areas of interest for trade. insdustrial
So, what do you think about yellow gold? Do you think there is a gold rush now, I'm totally sure ... Give your opinion below.

Thank you for reading,
