Tin

Atomic number: 50

Symbol: Sn

Category: post transition metal

Density at 25°C: solid:  from  5.769 g·cm−3 to 7.365 g·cm−3

Tin almost sounds so familiar as an element. For example tin cans. But are tin cans made of tin? Well the can itself is made of steel ( an alloy or iron) and it is coated with tin to provide corrosion resistance. 

Why the symbol Sn ? from the latin stannum, which at the time was an alloy
