Atomic symbol: Sn
Atomic number: 50
Atomic mass: 118.71
Appearance: Silvery-white or gray solid at 25°C
Group: 14
Period: 5
Series: Post-transition metals
Block: p

Mainly used in combination with other metals, both to make solder and to plate other metals.
Tin is alloyed with copper to make bronze.
Fun Fact! A high-pitched screeching sound is produced when a bar of tin is bent, known as a “tin cry”, due to the breaking of the crystal structure of the atoms.
