An Introduction to Gold, Its Symbol and Uses

Gold is a chemical element. Its atomic number is 79. Gold’s scientific symbol is Au. It is less chemically reactive than other metals. Gold is a good heat and electricity conductor. It is thick, supple, and lustrous metal. It may also be easily hammered into thin sheets or various shapes because it is malleable.


In the form of pricey jewellery, coins, and different works of art, gold has long been used as a symbol of wealth. From a scientific viewpoint, it has amazing qualities as well. Humans have treasured the chemical element gold for a very long time. In this article, you will find and learn important gold information along with the properties and uses of gold.

Discovery of Gold

Since ancient times, gold has been known to exist. Gold was used by civilizations like Ancient Egypt more than 5000 years ago. It has long been a valuable and wealthy substance. The Anglo-Saxon word "geology" for yellow gives gold its name. The Latin word for gold, "aurum," is where the letter Au derives from.

Properties of Gold

The following are the properties of gold:

  • Malleability: The most malleable metal is gold, which can be hammered into an incredibly thin sheet. 

  • Ductility: As one of the most ductile metals, it is also one of the easiest to stretch into a long wire.

  • Conducting: Heat and electricity flow through gold. The finest conductors are copper and silver, but gold connections outperform both of them because they never tarnish. The metal gold lasts long, but it stays conducive for a longer time. It is a very good heat and electrical conductor. When exposed to air and water, it is also one of the metals that resists corrosion and rust the best.  

  • Reflective Nature: Gold reflects heat and light very well. A small layer of gold is applied to the visors of the astronauts' space helmets; this gold is somewhat transparent. Even though it is so thin that the astronauts can see through it, the gold sheet lowers solar heat and glare.

  • A gorgeous metal aside, gold has other qualities. In normal circumstances, gold is a bright, golden metal. It is relatively soft yet very hefty and dense. 


Uses of Gold

The following  are some uses of gold:

  • Since the ancient period, gold has been utilised to create exquisite artefacts. Numerous of these items are still alive and on display at museums. 

  • Today, jewellery is frequently crafted from gold. Gold is frequently combined with another metal to produce jewellery because it is so soft. 

  • Due to its excellent electrical conductivity, gold is also used in electronics. Gold may reflect a lot of solar energy when it is applied in thin layers. 

  • They are employed on satellites to regulate temperature and on the visors of space suits to offer protection. To regulate the temperature inside big office buildings, they are also used to coat the windows.

  • Additionally, gold has been used as money. It was used to make coins in antiquity. Although other materials now make up the majority of currency, governments and institutions still hold significant quantities of gold in the form of bars. 


Interesting Facts about Gold

Here are some interesting gold facts:

  • A sheet, 300 feet broad by 300 feet long, can be created from one ounce of gold by pounding it. 

  • Previously, South Africa was the main source of gold for the entire world, but now China and Australia are the two countries that produce the most.

  • During the Middle Ages, gold flakes were occasionally sprinkled on the food of the affluent.

  • Light can pass through gold that has been beaten to a thin enough thickness.

  • Rocks all across the world contain gold. However, the majority of the time, there is so little gold present that it is invisible. Therefore, removing it from the rock is difficult. But gold is frequently discovered in rock that also contains lead and copper. Gold is also extracted together with these other components.

  • Larger deposits of gold can be found in some places. These appear where the surrounding rock has been gradually worn or washed away.  


Summary

Gold is a chemical element.  Its atomic number is 79 and its chemical symbol is Au. The most malleable metal is gold, which can be hammered into an incredibly thin sheet. As one of the most ductile metals, it is also one of the easiest to stretch into a long wire. It is a very good heat and electrical conductor.


In the past, gold was used as money or coinage. To make electrical connectors that are resistant to corrosion, gold is utilised in electronics, including computers. Gold is utilised in dentistry and medicine, including the treatment of some cancers (gold tooth). In this article, we have discussed the properties of gold as well as facts about gold that one must know.

FAQs on Facts about Gold and Its Uses

1. What is unique about gold?

The only metal that is yellow or "golden" in colour is gold. Other metals might turn yellowish, but only after they have oxidised or engaged in chemical reactions. Over 200 million years after Earth's formation, meteorites began tossing the globe, bringing nearly all of the planet's gold with them. 


Despite being a hefty, thick metal, gold is typically regarded as harmless. A noble metal is a bar of gold. It is comparatively non-reactive and does not degrade when exposed to air, moisture, or acidic environments. While most metals can be dissolved by acids, gold can only be dissolved by an exclusive combination of acids called aqua regia.

2. How is gold formed?

All of the gold that exists now on earth is thought to have originated in supernovae and neutron star collisions that took place before the solar system was established. In these situations, the r-process produced gold.


During the formation of the planet, gold sank to the earth's core. Only because of asteroid bombardment is it reachable today.


Gold might have been theoretically created through nuclear fusion, fission, and radioactive decay. The simplest method for scientists to transform gold is to blast mercury, which then decays to become gold. The sun can create several elements by nuclear fusion, but it cannot create gold. 

3. Where is gold found on the earth?

Gold is available in the crust and mantle in low concentration. Gold is also found as ore in rocks.
