Chemical element with atomic number 50 (Sn)
Tin
Tin is a chemical element; it has the symbol Sn and atomic number 50.
A metallic-gray metal, tin is soft enough to be cut with little force, and a bar of tin can be bent by hand with little effort. When bent, a bar of tin makes a sound, the so-called "tin cry", as a result of twinning in tin crystals.
