Bismuth (atomic number 83, symbol Bi) is a chemical element and a poor metal, resembling antimony and arsenic chemically. In nature, the element can occur uncombined, but its oxide and sulfide form ores with commercial importance. Bismuth is a silvery white metal, but surface oxide can make it appear pink in color. It is brittle, and its denseness is 86 percent that of lead.
Bismuth is a crystalline metal and the most diamagnetic of all. Except mercury, it has a lower thermal conductivity compared to other metals. Bismuth also has the highest Hall effect and a high electrical resistance. In...Read More
