The Silver Metal Lover

The story of Silver Metal Lover was set in the future when developing the robot. These robots are used not only for labor purposes but also for entertainment purposes. The extent of a special robot is designed to entertain people. They are golders, they are dancers, copper is an actor, and silver is a musician. When Jane first saw one of the silver, she was trapped by the completion of the robot. To possess him, she sold all belongings. For Jane he is no longer a robot, he is a real man, a beautiful lover.

In this article I will explain the production of gold, platinum and silver. Gold is a soft, bright yellow metallic element. From the stone age, gold has been highly appreciated. Platinum is a soft and malleable silver-white metal element. Platinum was discovered in Colombia in 1735. Silver is a shiny element of white metal. Since Babylonian era, silver has been used to earn money. I have studied these three, I will discuss its characteristics, application, production and its value.

The silver symbol is Ag and the atomic number is 47. Silver is a shiny white metal element that conducts heat and electricity more than any other metal. It is the most flexible of all metals. Excellent properties of silver include its excellent electrical conductivity and thermal conductivity. Silver is a rare metal that occupies less than 1 / 10,000 of the Earth's crust. Silver is one of the metals known for ancient civilization, gold, copper, iron, tine, lead, mercury. Pure silver is present in a large amount of metal and can be used without complicated separation and purification. It was very useful in Egypt before 3500 BC. Major silver producing countries are USA, Mexico, Canada, Peru, the Soviet Union, and Australia.

Pure (metal) bulk silver has the brightest white metallic luster with the highest electrical conductivity and thermal conductivity, with the lowest contact resistance among all metals. Silver is slightly harder than gold and more reactive than gold and platinum. Silver is hurt when exposed to ozone, hydrogen sulfide or sulfur-containing air by formation of silver sulfide, but silver is stable in pure air and water (CRC 2000). Silver has a higher light reflectance compared to other metals (Edwards & Petersen 1936).

Silver has the highest conductivity among all metals. In fact, silver determines conductivity - all other metals are compared. In the range of 0 to 100, silver level is 100, copper is 97, gold is 76. Because of this characteristic, and because sparks are less likely to occur, silver is generally used for circuits and contacts. Silver is also used for batteries that are reliable and suitable for weight restrictions, such as portable surgical instruments, hearing aids, pacemakers, and batteries for space travel.
