Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorification, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation.

The relative electronegativities of the Group VB elements in the trivalent state have been determined by methods based on thermochemical data and nuclear magnetic resonance and have the values 3·04 for nitrogen, 2·19 for phosphorus, 2·18 for arsenic, 2·06 for antimony and 2·16 for bismuth.

Because of its affinity for sulfur, antimony is often encountered as an admixture in the sulfides of arsenic, bismuth, nickel, lead, mercury, silver, and other elements. Physical and chemical properties. Antimony is known in a crystalline form and in three amorphous forms—explosive, black, and yellow.

• To obtain the usual values of arsenic, beryllium, bismuth, cadmium, chromium, cobalt, copper, mercury, methyl mercury, manganese, molybdenum, nickel, lead, antimony, vanadium, and zinc in the normal human body, the amounts of 15 metals were determined in 15 male and 15 Japanese cadavers (average weight, 55 kg [121 lb]).
