Silver is a soft metal that has a metallic white color and contains chemical elements. Silver is formed naturally, just like gold and many other metals. Commonly used to create metal coins other than gold and copper. However, it is very malleable and malleable. Strictly speaking, it is the most electrically conductive metal compared to others. To learn more about the components below, you can check out a few of them.
1. General description.
Silver has its own unique chemical symbol, i.e. Ag. 47 is its atomic number, and it is known as a transition metal. Its atomic weight is taken into account in g mol-1 and it has an electronic configuration.
At a temperature of 37 degrees Celsius, its density almost reaches 10.5 cm-3. When heated, silver melts at a density of about 9.3 g cm-3. It starts to melt when the temperature is around 961 degrees Celsius. The boiling point is even higher, around 216 degrees Celsius. It evaporates when the temperature reaches 250.58 kJ mol-1.
Silver has three degrees of oxidation. Based on the Pauling scale, its electronegativity is 1.93. Its atomic, covalent and van der Waals radii are 144, approximately 145 and 172 picometers. It has different ionization energies, i.e. 731 kilojol mol-1 for level 1, 2070 kilojol mol-1 for level 2 and 3361 kilojol mol-1 for level 3.
Although silver is more conductive than copper, it is not widely used for these purposes as copper. This is because silver can easily fade in nature and it has a higher price than copper. For these reasons, it is more commonly used for:
1. Jewelry. Jewelry and watches are common ways of using silver.
2. Utensils, household decorative items and utensils.
3. Movies for photography.
4. Electronic and electrical items, such as computer keyboards.
5. Dental equipment.
6. Mirrors and objects based on the optical apparatus.
7. Commercial use. For example, silver is widely used as a catalyst when it involves chemical reactions.
8. Textile industry. Silver ions are added to the polymer to produce yarn.
9. Medicinal use. It is known that this metal eliminates the presence of certain groups of viruses, fungi and bacteria. These microorganisms can be effectively eliminated, but it does not cause harmful side effects to humans.
10. Valuable ingots. Silver ingots have been widely created in various countries around the world. Some major sources of this metal come from copper, gold ores, zinc and lead. It can be found in chlorargirite and argentite, making it some kind of mineral. It is fascinating that this precious metal is found uniquely. Several countries have been recognized as the most active producers of this particular coin. These are countries like the US, Canada, Mexico and Peru. Quality ingots contain at least 99.9% of this precious metal, and these ingots are available for public purchase.
Due to industrial needs and the presence of competition, the price of silver has fallen dramatically, and since 2010 its average price has been $ 18 per troy ounce, or the equivalent of $ 588 per kg.
