Hello my fellow readers. My name is Silver. My name comes from the Anglo-Saxon word of Siolfur. Some people call me Ag for short (Ag stands argentum.) I am a white shinny metal. Since I am a white shinny metal argentum is the Latin word for white and shinning. I live in the periodic table of elements and my address is 47. I usually weigh 107.868. I am solid at room temperature. Copper and gold are my good friends and they make me strong and help me to be more durable.
You can find me almost anywhere. You can find me pure in silver ores and you can find me in structure forms in kitchens, jewelry stores, car shops, doctor offices, dentist offices, banks, and even in wallets. I am a very valuable metal. But although you can find me most anywhere, only 16% of me is used in coins and jewelry, while 40% is used to make photographic film. The rest of me is used in industries and health services. I am even used to make mirrors.
I am only slightly reactive and because of this I am placed very close to the bottom of the reactivity chart. I have very little uses in chemistry because of my low reactivity status. I don’t form oxides when I touch air but I do form silver sulfide when I touch polluted air. I form a tarnish when I interact with the hydrogen sulfide in the air, especially near industrial cities. The result of this is that I turn to silver sulfide. Tarnish is a dark, brown, or black film that develops slowly on me. Some silver tableware can tarnish because some food that you eat contains hydrogen sulfide. Hard boiled eggs are the perfect example of hydrogen sulfide. You can also sometimes see it in the dark ring around the yolk.
Sterling and I are used to make jewelry, cutlery and serving dishes. They are made of 92.5% of me and 7.5% of copper. Copper makes me harder, stronger, and more durable. I lie between gold and copper as one of the softest metals. I’m the best conductor of heat and electricity.
My friends, gold, platinum, mercury, and I make up the noble metals. We don’t oxidize readily when heated and we don’t dissolve in most mineral acids. I am a rare element because I’m the 68th in the elements in the earth’s crust. Because I am light sensitive, about 4/10 of me is used industrially to make film. The film is made of a plastic base over which is spread to a thin layer of gelatin that contains silver salt. This gelatin layer is known as the emulsion layer. Various salts are used in the emulsion. In iodide form, I react fastest to light and I am used for fast speed films. When I am in bromide form, I am slightly less sensitive and I am used for slower speeds. Bromide and chloride are light sensitive chemicals and are placed on the surface of developing papers.
My shell pattern is 2-8-18-18-1. I have 25 known isotopes including 9 nuclear isomers. My weight ranges between 102-117. I don’t react with diluted non-oxidizing acids (hydro-chloric and sulfuric acids) or strong bases (sodium hydro-oxide.) when I react with oxidizing acids (nitric or soncentrated sulfuric acids) I dissolve it and form a unipositive ion (Ag+.)
