WebBismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. WebWith these two-component catalysts, the first step, breaking the C-H bond, is catalysed by the more basic oxide, e.g. bismuth oxide. Molybdenum is involved in the next step - activation of a second hydrogen and insertion of an oxygen atom into the organic molecule. In this step molybdenum is reduced.
WebBismuth has a high electrical resistance, and has the highest Hall Effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field).
