tin 118 is a stable isotope of tin that does not decay. It has 68 neutrons and 50 protons, giving it a neutron-to-proton ratio of 1.36 which is fairly close to the magic number for nuclei that are especially stable. It is produced naturally and in nuclear fission. The element is available from American Elements in high purity as rod, pellets, pieces, granules and sputtering targets and as pure metal ingots.
Tin (Sn) is a silvery malleable metallic element that belongs to Group 14 of the periodic table. Tin is nontoxic and corrosion-resistant. It is often used in alloys with copper, such as bronzes and pewter. It is also used to plate steel cans and for tin-plate printing. Tin has been in use since ancient times. The earliest recorded usage is for coatings in the Bronze Age and it was used as early as 3000 bce in a wide variety of industrial applications, including plating iron to prevent rust, in tin cans, tin piping, type metals and low-temperature casting alloys.
Chemically, tin is reactive and forms compounds with chlorine and oxygen, forming the stannous chloride (SnCl2), which is used in tin galvanizing and as a reducing agent in the production of polymers and dyes; tin oxide, SnO, which is employed in making tin salts for chemical reagents and for plating; and tin fluoride, SnF2, which is used in some toothpaste. Organic tin compounds are used as biocides and fungicides.
