World Production of Copper, Silver and Gold. The 2004 figures for the world production of these metals was: gold 2,490 tonnes; silver 19,690 tonnes; and copper, 14,500,000 tonnes. Properties and Uses of Copper. Copper is often described as a 'salmon pink' metallic element, and was probably the first metal to be used by humans for practical purposes. Together with gold and the platinum-group metals, silver is one of the so-called precious metals. Because of its comparative scarcity, brilliant white colour, malleability, ductility, and resistance to atmospheric oxidation, silver has long been used in the manufacture of coins, ornaments, and jewelry. What is Gold? Native gold is an element and a mineral.It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties - some of which are unique to gold. These each give the gold distinctive colours; for example, gold that contains a significant amount of copper will be tinged red, while gold containing silver will be much paler than the distinctive and unmistakable bright-yellow of pure gold. Shared properties: Malleability(not the exact value, just the ability), ability to conduct electricity, ability to conduct heat, luster Specific properties: Melting point, density, color, boiling point Uses of Gold. The most common uses of gold is for making gold jewelry. It is also used to make glass that have red or purple colors. Electronic products like computers, telephones, and home appliances, industries, medical field, etc. all have some or the other uses of gold. Gold coins were very popular in the ancient world.

(where its superb properties as a conductor help offset its tremendous cost), Common Impurities:. What properties do copper gold and silver have in common? They are all non-ferrous metals, they are not magnetic, and they are also highly conductive and can also be used to conduct electricity. Properties of Gold. Gold is a radiant yellow color when found in mass, but can turn to colors including ruby, black and purple when divided into smaller fragments. Gold is the most malleable of metals, with a single gram capable of being beaten out to as wide a range as 300 feet. Silver has the greatest ability to transfer heat through its structure than any of the other metals. Young’s Modulus– Gold has the greatest ability to be hammered and stretched into long and flat shapes before losing its structural integrity. Hardness – Platinum is the hardest of the four precious metals. This means that you will have more success in scratching a bar of gold with a platinum coin than the other way around.

18 Sep 2019 Deposits of silver are much less common than deposits of gold or copper, yet by 3000 BC, methods had been developed for recovering silver from its ores, Some properties of the coinage metals are listed in Table 23.6.1.
Of all Precious Metals, Gold is the softest in terms of malleability. SILVER Silver is highly ductile, which makes it a popular metal for industrial needs. Electrical Visit this site to learn about Gold Properties and Characteristics. Most common substances, like Gold, exist as States of Matter as solids, liquids, A relatively soft metal, gold is usually hardened by alloying with copper, silver, or other metals. Isotopes : It has one stable isotope, 197Au; Reactivity with Non-metals : Gold 18 Apr 2007 Gold, silver and copper were the first metals that early humans came across. They would have These are the most common compounds of copper. The antibacterial properties of malachite have already been alluded to. 20 Jul 2006 Open University chemist Mike Bullivant outlines the properties of gold. recovered by archaeologists are fashioned from either gold or silver, which in the past 500 years, about 100, 000 tonnes of gold have been mined, but Generally, compared to platinum and palladium, gold and silver have a lower melting and boiling point, are better conductors, softer, more reflective, and more
Gold Nuggets from Colorado. These specimens range between three and eight millimeters across. These specimens range between three and eight millimeters across. They have the uniform color and rounded edges common of alluvial gold particles.
Silver has the greatest ability to transfer heat through its structure than any of the other metals.

Hardness – Platinum is the hardest of the four precious metals. This means that you will have more success in scratching a bar of gold with a platinum coin than the other way around. Copper is an element that is in the same family as gold and silver. All of these metals are in the same group on the periodic table. Because of their similarities in structure, these metals have similar properties.
