    broadway wholesale jewelry It is indeed rare and expensive, and there are some specials of gold. The physical properties of gold are relatively stable and not easy to have chemical reactions. The number of gold is limited. If it becomes gold, then gold will indeed depreciate. The element of aluminum is super valuable in the Napoleonic era. It is valuable than gold and silver. Later, the electrolytic aluminum appeared, and the aluminum depreciated

    because gold was currency. what.
    we the money we use now is a kind of credit currency, depending on whether the distribution is capable of issuing. Only the central bank is issued by the issuing currency. The Central Bank of China is the People's Bank of China. Go to see the money in your hand. Each one is printed.
    The "silver ticket" in ancient China is actually a kind of credit currency. It means the money we use now. Have you seen the Qiao family courtyard? When there is no silver, so many people will suddenly come to hold the silver ticket to get the silver, because in case the Qiao family really has no money, it will not be worth the text. In other words, how much credit currency you issued, you have to store the same amount of gold reserves. The country announces how much gold is stored every year, because this is the basis for how much the currency of this country is.
    For example, your money is like a proof that it belongs to prove that you have the other amount of gold. When we bought and sold, it was gold that was really traded.
    Whuro is the thing such as credit currency, that is, money, of course because -easy to carry. Just like N long time, human beings were "voids". Two bags of rice changed one sheep, and two sheep changed a ax (then productive forces), but when human beings developed, the horizon was farther. If people in the Central Plains want to buy seafood along the coast, will the sheep raising a group of sheep passing? Does the planting land carry 100 bags of rice away? You can't hang up a bunch of ax. Therefore, human beings need a "medium" of equivalent replacement. This "exchange medium" must be easy to store, portable, easy to identify, and easy to divide. In ancient times, shells, stones, money knives, etc. have been used as circulating currencies, but these cannot fully meet the above four conditions. After a long time of exploration, gold has adopted gold as circulating currency.
    First of all, it is stored. Gold is not like cattle and sheep, and it is not like the shell money knife will be corroded. How to toss or be gold, the diamond is still burn.
    It is carried. Have you ever played in the Stone Age, and the money in it is stone. You can pick it up in the game, but the reality is very inconvenient. When you carry the golden costume, you can see the costume articles, and everyone in his arms.
    then recognized. It is easy to distinguish gold and brass. Many people take the first action of gold to bite, and then the density color is very different.
    In the division, real gold is not afraid of fire, gold can be dissolved into a large and large amount of applicable volume.
    Summary: At present, gold is a currency that cannot be replaced. Can the currency be valuable? The money in your hand just represents gold. In other words, gold is money.

    The select

    The best answer
    Gold is a valuable metal and one of the earliest metals discovered and developed by humans. It is an important raw material for making jewelry and coins, and an important reserve material for the country. It is known as the "king of metal". It is not only considered a symbol of beauty and wealth, but also has its unique value for the interests of human beings.
    With the development of science and technology and modern industry, gold plays an important role in aerospace, medicine, electronics and other industrial fields. The use of gold is becoming more and more extensive, and consumption is increasing, which has aroused the world's attention and interest in gold.

    gold has good ductility. One or two pure gold can be hammered into a 1/100,000 mm thick gold leaf, which can be covered with an area of ​​nine square meters. When the sun passes, the golden leaves are transparent and the green light can be presented. 50 grams of gold can run eight kilometers, thin (1.6 less hair, 7).
    The volatility of gold is very small. Generally speaking, melting volatilization can be ignored. The evaporation of the gold in the gas is six times that of the air. The volatile speed is closely related to its impurities.

    The gold has good conductivity and thermal conductivity. Gold's conductivity is second only to silver and copper. It occupies the third position in metal, and its thermal conductivity is 74%of silver. The chemical properties of gold are very stable. Gold is not directly oxidized at low temperature or high temperature. At normal temperature, gold and inorganic acids, such as hydrochloric acid, nitric acid, and sulfuric acid, do not work, but mixed acids, such as water (three stems of hydrochloric acid and nitric acid) and cyanide solution, can dissolve gold well. The melting point of gold is 1063 degrees Celsius.
    If the gold is heated near the melting point, the gold can be melted like iron, and the small gold particles can be melted into fragments. The powder is in a low temperature state. It is necessary to increase the pressure and make it together. Gold can be made from other metals, such as gold, silver alloy, gold and copper alloy, gold and silver copper alloy, etc. In addition, there are so -called gold mercury alloys.

    The items are valuable Then the first factor is because of scarcity and unable to synthesize manually; simply speaking, it is a part of the use of part of the earth; This is also a reason why its prices and values ​​are worth collecting;
