Description
White metal; crystal system, fragile even in room temperature; weak electricity and heat conductibility; strong anti-magnetic; stable in the air; generate hydroxide with water; generate halide with halogen; soluble in acid hydrochloric, nitric acid and aqua regia; generate alloys with multiple kinds of metal; the compound is also used in medicine; alloys with lead, tin and cadmium are used as alloys with low melting point; usually exist in sulfide; also produced as natural bismuth;exist in the earth crust with the amount of 0.008ppm.
