7. Element uses Continued • Sprinklers • Glass • Ceramics • A catalyst in rubber production. • Pepto-Bismol.

8. Where The Element is Found • Can be found freely in nature • Found 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

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

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