Facts about gold
Here are a few interesting facts about the gold element.
- The name gold came from the Latin word “aurum”. (Aurum is the Latin word for gold).
- Gold is a very ancient element and it has been known since ancient times.
- South Africa produces around 2/3rd of the total gold which makes it a leading producer of gold in the world.
- Gold is available from earth’s crust as well as ocean.
- Around 78% of the total gold is used in jewelry.
Properties of gold
Here is a list of some physical properties and chemical properties of gold.
Physical properties of gold
- Gold is the only metal that has a yellowish lustrous surface.
- Gold metal can also conduct heat and electricity.
- Gold is ductile and malleable metal.
- Gold has FCC crystal structure.
- The density of gold is 19.3 g/cm3 and its atomic mass is 196.97 amu.
- The melting point and boiling point of gold is 1337 K and 3243 K respectively.
Chemical properties of gold
- Gold is highly resistive metal and it does not corrode.
- The common oxidation states of gold are +1 and +3.
- Gold is chemically inert to most of the acids, but it dissolves in aqua regia.
- The powdered form of gold reacts with chlorine to form AuCl3. This reaction takes place at 180 °C.
- At higher temperatures, gold shows chemical reaction with highly reactive element fluorine and forms gold (III) fluoride.
Uses of gold
Here are some uses of the gold element.
- Most of the gold (around 78%) is used in making ornaments and jewelry.
- In ancient times, gold coins were used as a currency.
- Medals and trophies are also made of gold metal.
