Silver has been known since antiquity and has always been considered a precious metal, even though it is dirt cheap in comparison to, say, gold. The price fluctuates daily, but it's not uncommon for silver to be 75 times cheaper than gold at any given moment.
The symbol for silver, Ag, comes from the Latin word argentum. In fact, the term silver is possibly first mentioned in the Bible, in the Book of Genesis. The Element Silver. Silver is an element in Group 11 in the Periodic Table of Elements, known as transition metals.
Element Silver - Ag. Comprehensive data on the chemical element Silver is provided on this page; including scores of properties, element names in many languages, most known nuclides of Silver. Common chemical compounds are also provided for many elements.
While silver itself is not considered to be toxic, most of its salts are poisonous. Exposure to silver (metal and soluble compounds, as Ag) in air should not exceed 0.01 mg/m 3, (8-hour time-weighted average - 40 hour week). Silver compounds can be absorbed in the circulatory system and reduced silver deposited in the various tissues of the body.

Silver is somewhat rare and expensive, although not as expensive as gold. Slag dumps in Asia Minor and on islands in the Aegean Sea indicate that man learned to separate silver from lead as early as 3000 B.C. Pure silver has a brilliant white metallic lustre. It is a little harder than gold …
Unlike other metals, silver and gold have been known to man since ages. The chemical symbol of silver is Ag, which stands for Argentum in Latin. The atomic number of Silver is 47, and the atomic weight is 107.8682 g/mol. Silver naturally occurs as a pure metal, and it reacts when exposed to ozone (O 3) and hydrogen sulfide (H 2 S). This element has 47 protons, 47 electrons, and 61 neutrons.
Silver's element symbol Ag, is from the Latin word argentum meaning silver.; In many cultures, and some alchemical texts, silver was associated with the Moon while gold was associated with the Sun.; Silver has the highest electrical conductivity of all metals. Silver …
One way silver is used is in alloys with gold. Gold is highly desired for coins and jewelry. But it is much too soft to use in its pure form. Adding silver to gold, however, makes an alloy that is much stronger and longer lasting. Most "gold" objects today are actually alloys, often alloys of silver and gold.
Silver, which is a brilliant white lustrous sheen when in its purest state, is also very ductile. Because silver is much stronger than gold, most gold jewelry in modern times is actually an alloy, or mix, of gold and silver. At normal room temperature it is in a solid state.
It isn't, gold(Au), silver(Ag) and copper(Cu) are all separate elements. But if you're talking about when they add copper or silver to gold, it's to harden it, so you can't bend it in your hands.

Silver tarnishes quite readily in air or water which have hydrogen sulfide or ozone. There are two natural, stable isotopes of silver, Ag-107 and Ag-109. Unlike most other elements on the periodic table, the natural occurrence of each of silver's stable isotopes is nearly equal. There are twenty-eight known radioactive isotopes of silver.
Silver is found naturally by itself, as an alloy with gold or in an ore (a rock containing various metals and elements). Silver is often found in copper and lead ores. The price of silver has fluctuated dramatically over the last century, climbing as demand increases but dropping when large silver deposits are found.
The vast majority of French silver found today was made after 1838 and will bear only two marks; Silver Guarantee & Maker's Mark. The left example shows the large guarantee mark (Minerve) & maker's mark. The right example the small guarantee mark (boar's head) and maker's mark. These marks are usually not in close proximity as shown in the ...
Silver has the atomic weight of 107.86 grams per mole, and its chemical symbol is Ag. It also has a melting point of 1,763.2 degrees Fahrenheit, and its density is 10.5 grams per cubic centimeters. In nature, this metal is found in argentite and ore deposits that contain other elements like gold or copper.
What is Silver - Silver Ag Element Periodic Table and Silver Facts Gold exists in the earth's crust at five parts per billion; Silver is present at 15 times that. Silver appears to be in abundance, but demand is rising (as discussed in our History of Silver in 21st Century article) while production is slowing.
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.
It has been instrumental in changing the course of history and no doubt the future possibilities are limitless for silver. Silver: The Element of Change. Visit our Silver Prices page for up to the minute silver prices or visit our silver price charts page to view historical silver pricing data.
Unlike gold, silver is present in many naturally occurring minerals. For silver the more important deposits commercially are such compounds as the minerals tetrahedrite and argentite (silver sulfide, Ag 2 S), which is usually associated with other sulfides such as those of lead and copper, as well as several other sulfides, some of which contain antimony as well.
Its lustre shine has been coveted since ancient times. It's not just rare or precious, as its more expensive cousin, gold, but there is evidence from as early as 3000 BC that humans extracted silver from naturally occurring silver sulphide deposits in rocks to make coins and jewellery.

Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table, copper and gold.Its 47 electrons are arranged in the configuration [Kr]4d 10 5s 1, similarly to copper ([Ar]3d 10 4s 1) and gold ([Xe]4f 14 5d 10 6s 1); group 11 is one of the few groups in the d-block which has a completely consistent set of electron configurations.
Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or to silver dust. The most dramatic symptom of argyria is that the skin turns purple or purple-grey.It may take the form of generalized argyria or local argyria.Generalized argyria affects large areas over much of the visible surface of the body.
