A characteristic of the silver

The silver is first metal one which a human being used. Calm gentle white luster is a characteristic, but the reflectance of the visible ray is the highest (with mercury) (as for the reflectance, 90%, the infrared rays reflect back 98%) and can start the brightness that is stronger than the platinum by what I polish in all metal. "argentum" that the silver symbol of an element "Ag" means "white brightness" in Latin is the etymology. In addition, I am full of expansibility, and heat and the electric conductivity are biggest among every metal. The silver is distributed over the natural world widely, but the gross weight is extremely few things if I compare it with other metal. In addition, a point included in in existing many minerals naturally is different from the money.
