S is for Silver
Silver is found in nature as both a mineral and an element.
Silver has a long history as a precious metal. It has been used extensively in ornaments, jewelry, silverware, and coinage. It has been used as the back of mirrors because when highly polished it reflects 95% of the available light back at you.
It used to be used in photographic film development. An important use today is as a disinfectant and antimicrobial.
It is harder than gold and more conductive than copper.
