What are the properties of silver?
Pure silver is nearly white, lustrous, soft, very ductile, malleable, it is an excellent conductor of heat and electricity. It is not a chemically active metal, but it is attacked by nitric acid (forming the nitrate) and by hot concentrated sulfuric acid.
Why is silver classified as a mineral?
Silver as a Native Element Mineral Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals. It persists there because silver does not readily react with oxygen or water.
What is silver mineral hardness?
Silver-white, tarnishes dark gray to black. Lustre: Metallic. Hardness: 2½ – 3.
What is silver material?
| references. Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: “shiny” or “white”) and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
What is silver mineral used for?
It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries.
What kind of resource is silver?
Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum.
How does silver mining work?
Silver ore is mined through both open-pit and underground methods. The open pit method involves using heavy machinery to mine deposits relatively near the earth’s surface. The remaining 72% comes from projects where silver is a by-product of mining other metals, such as copper, lead and zinc.

Why is silver unique?
Silver is the best electric conductor of the elements; all other elements are measured against it. It is the only element that scores 100% conductivity, with the next closest element being copper at 97%. 26. Silver is also the best thermal conductor of any metal but has the lowest contact resistance.
What is silver mineral?
Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching.

What are three physical properties of silver?
Body-centered Cubic. In a body-centered cubic (BCC) arrangement of atoms,the unit cell consists of eight atoms at the corners of a cube and one atom at the body center
What are 3 chemical properties of silver?
Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide.
