It is thought that tin has such a great multitude of stable isotopes because of tin's atomic number being 50, which is a "magic number" in nuclear physics. [citation needed] Tin is one of the easiest elements to detect and analyze by NMR spectroscopy, which relies on molecular weight and its chemical shifts are referenced against tetramethyltin ...
Tin is a chemical element with the symbol Sn (for Latin: stannum) and atomic number 50. It is a main-group metal in group 14 of the periodic table . Tin shows chemical similarity to both neighboring group 14 elements, germanium and lead and has two possible oxidation states , +2 and the slightly more stable +4.
This is probably related to the fact that 50 is a "magic number" of protons. In addition, twenty-nine unstable tin isotopes are known, including tin-100 (100 Sn) (discovered in 1994) [4] and tin-132 (132 Sn), which are both "doubly magic". The longest-lived tin radioisotope is tin-126 (126 Sn), with a half-life of 230,000 years. The other 28 ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
