Bismuth structure with space group

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 WebArsenic Group. Although long thought to be stable, bismuth, as an element, was shown to be weakly radioactive, with an enormously long half-life period: 1.9 × 10 19 years (de …
