Where The Element is FoundCan be found freely in natureFound in minerals like bismuthine (Bi2O3) and in bismuth ochre (Bi2O3). Abundance of Bismuth: Earth's Crust/p.p.m.: 0.048 Seawater/p.p.m.: Atlantic Surface: 5.1E-08 Atlantic Deep: N/A Pacific Surface: 4E-08 Pacific Deep: 4E-09

Chemical PropertiesReacts with most acids, halogens, air, and water Combines slowly with oxygen at room temperatureBismuth oxide (Bi2O3) gives the metal its pinkish or yellowish tinge.Oxidation States: +5,+3

Interesting FactsCan form beautiful crystals In the early times it was confused with tin and leadIt is generally considered to be the last naturally occurring stable, non-radioactive element on the periodic tablefrom German Wismuth, which means white mass http://www.youtube.com/watch?v=vyIo-c7VmIM
