Answer:
less the 50% of all the world's gold is still in the ground
the largest gold nugget ever found weighed 195 pounds
the term "gold" comes from an old Anglo-Saxon world 'gelo', or yellow
It is able to conduct electricity and heat
gold never rusts
Chemical symbol is Au from the Latin word 'aurum' which means "shining dawn"
copper and gold were the first metal to be discovered by man
native Scottish gold is the purest, at 22.8 carats
Gold is an element that is a chemical element. It was discovered in circa 3000 BC circa 3000 BC. The boiling point is 2807.0 °C and melting point is 1064.43 °C. It's a high quality valued metal. AU is the symbol from its latin name aurum. Chemically, gold is a transition metal and can form trivalent and univalent cations upon solvation.
Electron shell diagram of gold Gold is the most malleable and ductile metal.Gold is a good conductor of heat and electricity, and is not affected by air and most reagents. Heat, moisture, oxygen, and most corrosive agents have very little chemical effect on gold, making it well-suited for use in coins and jewelry. The usual grey color of metals depends on their "electron sea" that is capable of absorbing and re-emitting photons over a wide range of frequencies. Gold can be made into thread and used in embroidery. Gold can be used in food. There are many types of gold such as colloid gold. It is made tightly. Many competitions, and honors, such as the Olympics and the Nobel Prize, award a gold medal to the winner. Gold is used as the reflective layer on some high-end CDs. Common uses of gold, precious metal, currency, coinage, jelwery, tablewear, and many more! Gold was discovered in Ancient times and used by the ancient South Americans, Asians, Egyptians, Greeks, Romans and Chinese. It is also used in the bible several times. Pure gold is non reactive and is skin friendly. If you suffer from any skin problem, may be your gold item has been mixed with some other metal, which is reacting and causing some kind of allergy. Gold can be molded to give any shape. You can even prepare super thin gold sheets. To be called solid gold it has to be a minimum of 10 Karat. Gold is mixed with other metals to change the natural color of the gold, which is yellow gold. For example if you mix copper, the resultant is pinkish in color while silver blending leads to a nice greenish shade.
Gold is a chemical element with the symbol Au (from Latin: aurum, "shining dawn") and an atomic number of 79. It has been a highly sought-after precious metal for coinage, jewelry, and other arts since the beginning of recorded history.
The metal occurs as nuggets or grains in rocks, in veins and in alluvial deposits. Gold is dense, soft, shiny and the most malleable and ductile pure metal known. Pure gold has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. gold is a transition metal and can form trivalent and univalent cations in solutions. Compared with other metals, pure gold is chemically least reactive, but it is attacked by aqua regia.
Gold is the most malleable and ductile of all metals; a single gram can be beaten into a sheet of 1 square meter, or an ounce into 300 square feet. Gold leaf can be beaten thin enough to become translucent. The transmitted light appears greenish blue, because gold strongly reflects yellow and red. Such semi-transparent sheets also strongly reflect infrared light, making them useful as infrared (radiant heat) shields in visors of heat-resistant suits, and in sun-visors for spacesuits.
Gold readily creates alloys with many other metals. These alloys can be produced to modify the hardness and other metallurgical properties, to control melting point or to create exotic colors Gold is a good conductor of heat and electricity and reflects infrared radiation strongly. Chemically, it is unaffected by air, moisture and most corrosive reagents, and is therefore well suited for use in coins and jewelry and as a protective coating on other, more reactive, metals. However, it is not chemically inert.
Gold is highly malleable, ductile, and valuable.
The symbol origin is from the Latin word aurum meaning gold.
Less than 50% of all the world's gold is still in the ground.
Gold never rusts.
Native Scottish gold is the purest, at 22.8 karats.
The origin of it's name is from the old English word geolo meaning yellow.
