1. Gold is the most malleable and ductile of all metals. This means it can be beaten into thin sheets or drawn into a thin wire without breaking.
2. Gold is actually incredibly rare and scarce. Every year, around 3,000 tons of gold is mined around the world and yet, if it were all collected together, it would fit into a space of only 20m x 20m x 20m.
3. Gold is believed to have been in use since at least the year 3,000 BC. It has been used as a form of currency, jewellery and to make a variety of decorative objects over thousands of years. It is even said that the first coins were made from gold in the 7th century BC by King Croesus of Lydia, in the Western part of modern Turkey.
What is gold facts for kids?
Gold Facts for Kids:
Gold is an element, and its atomic symbol is Au (Aurum, in Latin). It is an extremely rare metal that is highly resistant to corrosion and oxidization, meaning it won’t easily rust, scratch or tarnish.
Despite its rarity and strength, gold is one of the softest and most malleable of all metals. It can be easily cut and shaped, making it a popular choice for jewelry and other decorative items.
Gold is mostly found in its pure state mixed with quartz and other rocky minerals. It can also be found in riverbeds and in the ocean. It is mined in many places and has been for centuries, with some of the earliest mines dating back to ancient cultures.
Gold has been a valuable commodity and a symbol of wealth for many centuries. Its value remains high today; it is often used to create coins, jewelry, and electronics parts.
Gold can be used in electronics because it conducts electricity and is not subject to corrosion. Gold is also used in medical applications, such as in Magnetic Resonance Imaging (MRI) machines, dental crowns, and pacemakers.
Gold is also used in jewelry because of its attractive color, malleability, and durability. Gold is also non-reactive, meaning it won’t react with skin or the environment in the way that some other metals will.
Although gold is a valuable and desirable metal, it is also necessary to take care of it in order for it to retain its shine and luster. Too much exposure to water and certain chemical compounds can cause gold to discolor and deteriorate.
What’s so special about gold?
Gold is a precious metal with many special qualities that make it a desirable commodity. It is the most malleable and ductile metal, meaning it can be shaped, hammered and drawn into thin wires. It is also one of the few elements that does not corrode; it is non-toxic and can be alloyed with other elements to create a variety of useful applications.
Gold has a high luster, so it can be used for various decorative applications as well. Gold jewelry is not just beautiful and elegant, but it is also hypoallergenic and durable, lasting a long time without tarnishing.
Gold also has a long history and has been associated with power, wealth and greatness. Governments have used gold to back their currencies and it was viewed as an asset that was portable, divisible and reliable.

How old is the gold on Earth?
The gold present on Earth is estimated to be around the same age as the Earth itself, which is about 4. 5 billion years old. Gold is believed to have been present since the Earth’s formation, created when supernovas exploded and sent particles of heavy elements like gold in every direction.
This primeaval gold, as it is referred to, has developed and dispersed across the planet over millions of years, winding up in various reservoirs, including ore deposits. Much of the gold used in modern day jewelry, coins, and other products has not been sitting in the Earth for millions of years, but has grown increasingly extracted over time.
How was gold born?
Gold was born out of stellar nucleosynthesis, the process by which elements heavier than helium are synthesized in the cores of stars. This process occurs when atoms in a star fuse to form new elements.
During nucleosynthesis, larger atoms are created from smaller atoms, releasing energy in the process. It is thought that most gold present in the universe was created in the explosive death of massive stars, or supernovae, when the core of the star collapses.
This results in the fusion of elements producing gold, among other elements. Gold is also created in collisions of neutron stars, two very dense stars that are orbiting each other and that eventually spiral inward and collide.
The extreme heat and pressure released by the collision of these two neutron stars is thought to further fuse elements, including gold. Though small amounts of gold exist on Earth, this gold is a result of being deposited here through asteroid or comet impacts, rather than forming on our planet.
What can destroy a gold?
Gold is an incredibly durable metal that does not corrode, rust, or tarnish. In fact, it is one of the most stable elements. However, it can still be subject to destruction if the right conditions are met.
Gold can be destroyed by extreme levels of heat, strong acids, and strong bases. When exposed to extremely high temperatures, such as that of a furnace or a foundry, gold can melt and be irreparably altered.
Hydrochloric acid, also known as muriatic acid, is a powerful acid that can dissolve gold, as can nitric acid. Lastly, strong bases such as caustic potash or caustic soda can be used to dissolve gold, leaving it in a destroyed state.
What is the rarest than gold?
The rarest element on Earth is francium. It is the second-most reactive element and the last element in the alkali metal group on the periodic table. Francium occurs naturally on Earth in traces, with one-quadrillionth the abundance of gold.
It is found in uranium ores, but only in an average of one atom per 10,000-quintillion atoms of uranium. Francium is radioactive and has the most unstable nucleus of all elements in its natural form.
The element has a half-life of just 22 minutes so has to be synthesized in labs and only in small amounts. It is so rare that the number of atoms of the element present in the Earth is estimated to be less than an ounce.
Additionally, it is highly expensive to produce in a lab, with the cost of one gram of francium estimated to be around $1 billion USD. These properties make francium significantly rarer than gold.
Does gold ever get dirty?
Yes, gold can get dirty, though it is less susceptible to tarnishing than other metals. It is possible for dirt and grime to accumulate on gold from everyday exposure, particularly if the gold is worn as jewelry or used to form home decor elements.
To keep gold clean, people can use warm water and mild dish soap with a soft cloth or brush to remove dirt or dust buildup. Such methods should be used with caution and followed by rinsing the item with fresh water and drying it with a soft cloth.
Other methods of cleaning gold may require specialized solutions and jewelry cleaners and should only be used with the appropriate instructions.
What makes gold unique?
Gold has a unique set of properties that make it uniquely suited to many applications. It is one of the heaviest metals that can be found on Earth and it is corrosion resistant. These two factors make gold particularly valuable for many uses, including jewelry, coins, and industrial production.
Gold also has several other properties that make it attractive for use in a variety of applications. It is a highly conductive metal, which makes it useful for electronic equipment and circuit boards.
Gold’s ductility and malleability also make it ideal for use in jewelry and other decorative items, such as dental fillings. Finally, gold is chemically inert, making it exceptionally stable, which is why it is considered an ideal material for coinage, a reliable store of value, and a hedge against inflation.
All of these qualities make gold a rare and valuable metal that has been sought after throughout history.
Why is gold unique among the metals?
Gold is unique among the metals for a variety of reasons. It is a very special metal that has been prized for centuries for its beauty, value, and versatility. Gold is one of the softest of all metals which allows it to be easily worked into intricate designs that other metals could not easily achieve.
