Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO 2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable

Tin foil was once a common wrapping material for foods and drugs; replaced in the early 20th century by the use of aluminium foil, which is now commonly referred to as tin foil, hence one use of the slang term "tinnie" or "tinny" for a small aluminium open boat, a small pipe for use of a drug such as cannabis, or for a can of beer. Today, the ...
Cassiterite is a tin oxide mineral, SnO 2.It is generally opaque, but it is translucent in thin crystals.Its luster and multiple crystal faces produce a desirable gem. . Cassiterite was the chief tin ore throughout ancient history and remains the most important source of t
This created the demand for rare tin metal and formed a trade network that linked the distant sources of tin to the markets of Bronze Age cultures. Cassiterite (SnO 2 ), oxidized tin, most likely was the original source of tin in ancient times.

Tin-121m (121m Sn) is a radioisotope and nuclear isomer of tin with a half-life of 43.9 years. In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce tin-121 at higher yields. For example, its yield ...
