The core of large stars, especially during a nova. Gold is an element and is formed in the core of large stars, especially during a nova. On Earth, veins of gold are formed by separation from liquid rock after gravity agglomer.
Gold is not formed on the Earth like diamonds and many other gems and minerals. Instead, most scientists now believe that gold actually came to earth from outer space in large meteorites that have struck the planet over billions of years. While diamonds can be artificially produced, there is only so much gold available on the planet. It cannot be created in a lab the way that many gemstones can be. While some scientists believe that gold mining in outer space may be the bonanza of the future, such dreams are currently too expensive to be realized. Gold is an element and is formed in the core of large stars, especially during a nova. On Earth, veins of gold are formed by separation from liquid rock after gravity agglomer … ates the molecules. It will form long chains within spaces in minerals because of its resistance to combining with lighter elements. Gold isn't a rock. It is a chemical element, or, in the eyes of the geologist or miner, it is a mineral. It is … sometimes referred to as a noble metal because it doesn't react easily with other stuff in the earth. That translates into gold appearing as a pure metal in the form or tiny flakes, nuggets or the like. On Earth, gold is found in ores in rock formed from the Precambrian time onward. It most often occurs as a native metal, typically in a metal solid solution with silver (i.e. as a gold silver alloy). Such alloys usually have a silver content of 8–10%. The oxidation state of gold in its compounds ranges from −1 to +5, but Au(I) and Au(III) dominate its chemistry. Au(I), referred to as the aurous ion, is the most common oxidation state with soft ligands such as thioethers, thiolates, and tertiary phosphines. Au(I) compounds are typically linear. The process of erosion had sloughed fragments of gold from the reef into the gully. - Robyn Annear. Ancient Greeks believed that gold was formed by the rays of the sun transforming common metals in the earth. Scientists today still think that gold formation is related to stars, specifically dying stars. At the core of a dying star-a supernova-elements begin to fuse together in the extreme heat.  Gold is not formed in rock so much as it will tend to concentrate under certain geologic conditions. We see evidence of gold grains in some rivers, and nuggets in some rock formations. Gold isn't a rock. It is a chemical element, or, in the eyes of the geologist or miner, it is a mineral. It is … sometimes referred to as a noble metal because it doesn't react easily with other stuff in the earth. That translates into gold appearing as a pure metal in the form or tiny flakes, nuggets or the like. Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The oxidation state of gold in its compounds ranges from −1 to +5, but Au(I) and Au(III) dominate its chemistry. Au(I), referred to as the aurous ion, is the most common oxidation state with soft ligands such as thioethers, thiolates, and tertiary phosphines. Au(I) compounds are typically linear. Answer 1: Gold, in its pure form is not made-it occurs naturally in an elemental form. On a side note, the history of alchemy was largely based on the desire of people (probably kings!) to combine other (cheap and abundant) elements and compounds to make gold. Most of the gold products such as jewelry, etc., have a rating in karats, as you probably already know. Gold is an element and is formed in the core of large stars, especially during a nova. On Earth, veins of gold are formed by separation from liquid rock after gravity agglomer … ates the molecules. It will form long chains within spaces in minerals because of its resistance to combining with lighter elements. Remember that gold is an element, and it isn't made or formed in nature so much as it is a part of the mix of the things that make up the earth's structure.

Best Answer: Gold was formed in the sense of being placed on the earth when the earth was formed by cooling down from gas ejected by the Sun some 4.5 billion years ago. Gold deposits were laid down as rocks formed as part of that cooling process. The amount of gold in the earth has been constant since then. None has been made on earth, either naturally or by alchemists (who dreamed of turning lead into gold).
