The element Silver is a well-known element on the periodic table worldwide. Known for its beauty, Silver is one of the precious metals along with gold and platinum. Although silver is a frequently talked about element, most lack in depth knowledge of its characteristics, history, and usage.
The characteristics and properties of silver are what makes it a precious metal. In its pure form silver is a white, soft metal. Silver is extremely soft so a small amount of another metal is usually added to increase its hardness and strength. A metal silver is usually mixed with is copper. The element silver reflects 95 percent of light that strikes it, which makes it the most shiny of all the metals on the periodic table. The metal is located on the D

Silver was one of the first of five metals to be used by human beings. The uses of silver vary from money, jewelry, ornaments, and utensils to electricity, medicine, and technology. Silver has been used in the economic systems of many major cultures. Silver is known as a coinage metal because it has been used to make coins for thousands of years (Helper, 2016). The denarius was a silver coin used by the Romans during the periods of the Republic and the Empire. The coin was first issued in about 211 B.C. (Doty, 2016). In the past, the United States also used the metal for coins. The uses of silver for jewelry is mainly because of the metals property of reflecting light. The metal shines brilliantly so it would be understandable why so many generations of humans have used the metal for beauty purposes. Silver is also used to make mirrors because of it property of reflecting light. Silver is used by the electrical industry for wires and other items today. Silver is used a lot in these industries because it conducts electricity better than any other metal. Silver is also surprisingly used in medicine today. Doctors use plates, wires, and drainage tubes made of silver. Doctors use silver equipment because silver helps kill bacteria (Helper, 2016). Silver compounds also have many uses. In medicine silver nitrate is used to cauterize wounds to prevent bleeding and infection. A mild solution of silver nitrate is used to treat certain eye and skin diseases. In the photographic industry silver nitrate is used in making film. Most silver salts used in film are made from silver nitrate. An example is silver bromide photographic film. It is made of silver nitrate and a potassium bromide solution (Belanger, 2016). Silver is used all around us in places many did not know

It is used in the production of dyes, fertilizers, and chlorides as well as in electroplating and in the photographic, textile and rubber industries.
Molybdenum is a transition metal. It is represented by the symbol Mo. It is a pure metal that is is silverish white in color and very hard, and has one of the highest melting points of all pure elements at 4753 °F. Its boiling point is 8382 °F. Its density is 10280 kg/m3 and its hardness is 5.5.
Elements are the basic building blocks of matter due to the fact that they are chemically the simplest substances. Whether we can find them in the air or in our gold/silver necklaces, elements are everywhere! One essential element is hydrogen, the first element on the period table (located under Group 1 as an alkaline metal) is composed of a single proton and electron; therefore having an atomic number and atomic mass of 1 and electron configuration of 1s1. In fact, hydrogen is the lightest, simplest and most commonly found chemical element in the universe (it makes up about 90% of the universe by weight). Interestingly enough, the heavier elements on the periodic table were either made from hydrogen or other elements that were made from hydrogen. The most common isotope formed of hydrogen is protium, with 1 proton and no neutrons. Hydrogen can also exist as both positively or negatively charged. The physical form of hydrogen at room temperature is a colorless and odorless gas. Hydrogen gas is extremely flammable and because of this chemical property, it is used as fuel for the main engine of space shuttles. Hydrogen is an important element and has received a lot of recognition throughout history for its usefulness.
I am going to discuss about the element known as gold in my assignment. To describe the element gold in simple terms, I can only say that it is an element (chemical element). This element is denoted by the symbol Au. It has an atomic number of seventy nine (79). I will describe quite a number of things concerning gold as an element. To begin with is:
In chemistry, out of all the elements on the periodic table, there are a few that stand out because of certain characteristics, Gallium is one of these elements. On the periodic table, Gallium has the symbol Ga and atomic number 31. Gallium is a metal that has uses in such things as, medical, industrial, and everyday life.
Gold was extremely valued by the Ancient Egyptians. It symbolised the halo of the god and this was identified to be very significant because gold was known as the symbol of immortal life. People of social or religious consequence were often hidden in ornament inlaid with or create of solid gold. Gold was also especially popular during the Roman history. When the metropolises and culture started to develop, Rome called out brilliant experts who could make a wide spectrum of jewellery such as rings, necklaces, circlets and earrings. Recent history scholars trust that the convention of wearing a ring to represent a commitment appeared from the Roman generation. Over time the Romans stretched the application of gold beyond jewellery and it started to make ornaments and other everyday objects of the upper class. The existence of many gold in the house was a symbol of power and wealth.
Potassium is a solid silvery white element. It is soft and can be cut with a knife. Potassium is the least dense known metal, besides lithium. It is the seventh most abundant element. It makes up about 1.5% by weight of the earth's crust. It decomposes in water because of the hydrogen. It usually catches fire during reaction with water.
Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2ºC and boils at 2500ºC. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is light, easy to shape and can be strong. This makes aluminum one of the most used metals in the world, right behind iron and steel. (Geary, 185) In its pure state, aluminum is quite weak compared to the other metals. However, its strength can be greatly increased by adding small amounts of alloying elements, heat-treating, or cold working. Only a small percentage of aluminum is used in its pure form. It is made into such items as electrical conductors, jewelry, and decorative trim for alliances and cars. A combination of the three techniques has produced aluminum alloys that, pound for pound, are stronger than structural steel. Some common metals used in alloys for aluminum are copper, magnesium and zinc.(Walker, 31) The added elements give the aluminum strength and other properties. (Newmark, 41) Aluminum is one of the lightest metals. It weighs about 168.5 pounds per cubic foot, about a third as much as steel which weighs 487 pounds per cubic foot. (Neely, 214) As a result, aluminum has replaced steel for many uses. For example, some ...
In chemistry, metals compose a great number of the periodic table elements. Each metal has its own characteristic mass,
