Silver: Soft, White, Lustrous Transition Metal

The silver coin is a symbol of strength and the moon because it is malleable and ductile but it also can be reformed and shaped easily but it wasn’t as protective as the gold coin.

Every year there is 1.3 billion tons of steel produced around the world. Steel is made in different sizes and categorized by how good the steel is, these is called grades and standards. Steel today is used in many things you wouldn’t even think of such as the armored vests policemen wear or jewelry. Stainless steel was invented in 1913 by Harry Brearley when he put 12.8% chromium and .24% carbon when the standard for steel was .12 - 2% carbon and 16 - 26% chromium. Stainless steel is used in almost all new home appliances and in Great Britain it was used for cars. Some buildings made with steel are the Chrysler building, the Empire State Building, and the Sears Tower. Another building made with tons of steel is the Burj Khalifa. It used 55,000 tons of steel to be made and at 2,717 feet it is the tallest building in the

The city of Potosi, which is now modern day Bolivia, was once a vast mining town located in the Andean highlands in the mid 1500’s. This town was the world’s leading producer of silver; the mountain contained enormous amounts of silver that then created many opportunities for many different people all around the world. The population of Potosi at this time was around 160,000 large enough that it was comparing to that of cities like London and Amsterdam. This great mountain supplied many people with all sorts of different jobs. This was a very dangerous and fatal job for the people and many ended up dead or injured from working in the mines. “Once inside, they spend the whole week in there without emerging, working with tallow candle. They are in great danger inside there, for one very small stone that falls injures or kills anyone is strikes. If 20 healthy Indians enter on Monday, half may emerge crippled on Saturday” (Strayer614). Mining in this mountain was very risky and you never knew if you would survive the day or make it out of mine safely.

It is necessary to identify the identity of two unknown metals. This is important because a metal scrap yard must know the identities of the metals before they can be recycled. It is also necessary to know what each metal is if a building is to be made using one or more of these metals. Identifying the metals will be done using intensive properties. Intensive properties do not depend on the amount of material present. Density is an intensive property found with the formula D=m/v. Which is defined as mass divided by volume to find the density.

Colloidal silver for dogs is beginning to become the next trendy thing in holistic dog medicine. It’s no surprise, really. Colloidal silver has been making a name for itself among humans for the past several years. The real question is this: is it effective, and is it safe?

The abundance of silver will depend on how it is measured and calculated, in this instance the abundance in the Earth's crust for silver is 0.080 (ppm)3. Measuring parts per million in mass, but again depending on the method chosen to estimate it will vary, but because silver is a precious metal it is not very abundant making them active just not chemically active for Earth's crust. Silver comes from the old English word seolfor. Silver is located in the reserves of Western United States, Mexico, Peru, Canada, China and as well as in Australia and Poland. Silver in its original state or in other words natural form can look like an ore possibly as chlorargyrite, argentite, galena a lead ore in which makes it almost effortless to see/ identify.

This experiment was performed to observe the formation of silver chromate from a reaction between silver nitrate and potassium chromate. In this double displacement reaction, the cations and anions of the two reactants swapped and produced silver chromate and potassium chromate. An indication of a reaction occurring between the silver nitrate and potassium chromate was the production of a red solid from the yellow potassium chromate and the clear silver nitrate. Potassium nitrate has its uses in applications such as fertilizers and food preservation while the other product of this reaction, silver chromate, has little application in the real world.

Sterling silver is a combination of silver containing 92.5% by mass of silver and 7.5% by mass of different metals, like copper and other. The sterling silver standard has a base millesimal fineness of 925. When we talk about fine silver it is of 99.9% pure which is soft and shiny in quality. It is used for making various types of silver jewelry, coins and many other precious objects.Sterling silver is quite different form pure silver. It contains 92.5% silver and the rest are other metals used in it to make something. The silver is generally alloyed with copper to give it quality while protecting the pliability and appearance of the valuable metal. It is originated in Europe as early as the 12th century in the area that is now northern Germany.

Since silver is soft, jewelry grade silver is actually an alloy or blend of silver with harder metallic compounds, with sterling silver being the most common alloy.

Gold was discovered in 1847 by General John A. Sutter. Gold was found in a saw mill. They noticed something shiny at the bottom of a ditch. Once they discovered it was gold they dug more and found a lot of it. Gold’s symbol is Au, the Atomic number is 79, the average atomic mass is 196.967, gold-179. 36 is the only naturally occurring isotope of gold, its state of matter is solid, and it is not synthetic.

Arsenic has an atomic number of 33 and a relative atomic mass of 74.922amu. Arsenic is an odd element, as it acts like metal even though it is a natural element. Arsenic is found in natural environments, and in limited quantities found in rocks, soil, water and more. Arsenic was very known to the ancient Egyptians and the Chinese, they used Arsenic as a way of gilding metals. The orpiment(As2S3) and the realgar (As4S4) : are the two Arsenic sulphide minerals that Greek Philosopher, Theophrastus. As2O3 is the trioxide, is one of the end products of copper refining. This is a form of arsenic that has also been known for awhile now, and it is called white arsenic. The official discovery of arsenic is to Alberts Magnus in around the 1200s. As to the physical property, it is radiant, has a silver colour and fragile, as it is a semi-metal. When in exposed to air, it is rapidly damaged, because of the usual elements in air, such as nitrogen and more. Arsenic is not particularly used in any technology, but recently we use Arsenic in semiconductor gallium arsenide, it can convert electric currents to laser lights. Usually it is not used

Gold is usually found together with copper in nature, but at this time, due to it's physical features, was only used for jewellery and medals.

     Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society.

In general, nanometal particles already have numerous applications. One of the most important ones is in medicine. They can be used to deliver drugs to specific regions of the human body (mostly used for tumors), they can act as antioxidants or even treat people with chronic bacterial diseases.[9] An additional use of nanometal particles, is in electronics as they are being used to produce low-cost electrodes for fuel cells and are used as a coating to the anodes of
