WebIt has a half of life of 2x10 19 years, I would round off as the same as eternity so. The density of the metal is 9.8, little less than lead but like water, the solid expands as it freezes and it floats on the liquid. It can melt quite easily and it can grow stunning little ziggurat like crystals by cooling it slowly from melt. It is easy. Webbismuth (Bi), the most metallic and the least abundant of the elements in the nitrogen group (Group 15 [Va] of the periodic table). Bismuth is hard, brittle, lustrous, and coarsely crystalline. It can be distinguished from all other metals by its colour—gray-white with a reddish tinge. History
