Samples of the element tin (Sn) rotating. Tin has the atomic number 50, and is a malleable post-transition metal. It has one of the longest histories of use by humans despite its relative scarcity, and was a component of the bronzes that gave the Bronze Age its name, dating back to some 3500 BCE. Today it is still used in numerous alloys, and imparts corrosion-resistance to steel. | |
