Characteristics and main properties of silver

Silver is a chemical element whose symbol is Ag, being a noble, transitional metal with an intense bright white color. Among its characteristics, it should be noted that it is a soft, ductile and malleable metal. It has a diversity of both industrial and leisure uses, for example jewelry. We have already advanced some of its characteristics and properties such as that it is soft but not as soft as gold, and this makes it somewhat difficult to work with it especially when it comes to jewelry pieces. This is why it is normally mixed with other materials to obtain various pieces. High electrical conductivity It should be noted that silver has the highest electrical conductivity and thermal conductivity of all metals. But it has many other applications due to its somewhat more expensive price. White shine It also stands out especially for having a metallic white shine and is what makes it widely used in jewelry. It is rarely found in its pure state. It is another of its characteristics because of the quality. of silver is established based on the so-called 0.999 law, which measures the proportion of pure silver over a global 1,000 parts of metal.Atomic properties Mean radius 160 pm Electronegativity 1.93 (Pauling scale) Atomic radius (calc) 165 pm ( Bohr radius) Covalent radius 153 pm Van der Waals radius 172 pm Oxidation state (s) +1, +2, +3, + 4 Amphoteric oxide 1st ionization energy 731 kJ / mol2. Ionization energy 2070 kJ / mol3.Ionization energy 3361 kJ / mol Physical properties Ordinary state Solid Density 10490 kg / m3 Melting point 1234.93 K (962 ° C) Boiling point 2435 K (2162 ° C) Enthalpy of vaporization 250.58 kJ / mol Melting enthalpy 11.3 kJ / mol Vapor pressure 0.34 Pa at 1234 K. What are the applications of silver? It has various uses, although the vast majority belong to industry, then there are monetary purposes, and those of goldsmithing, photography and chemistry. It is also noteworthy that other of its applications are the bladed weapons that were used since prehistory, it also has uses in medicine such as the so-called silver nitrate, also in the contacts of electrical generators of diesel-electric locomotives, in the sector of electronics, due to its high conductivity; for the manufacture of coins; For jewelry being authentic pieces of silver, something that has a lower value than gold. Other uses of silver are in dentistry, as a catalyst in oxidation reactions, in the assembly of computers and other devices.
