83 Bi Bismuth

Metal, mass: 208.98 u, no stable isotopes, abundance rank (earth/space): 65/73

Bismuth Bismuth 2
Bismuth is mostly used in low-melting alloys. In pure form it can grow beautiful crystals. It has long been thought to be the last stable element, but in 2003 its radioactivity was discovered. The natural isotope209Bi has an extremely long half-life of 1.9*1019 (19 quintillion) years and therefore is harmless even in large quantities. It decays to thallium.
