WebBismuth is without doubt a heavy metal; It occurs so low in the periodic table many were puzzled by the fact that it didn't seem radioactive. In fact its major isotope bismuth-219 was predicted to be so back in 1949. But it wasn't until 55 years later, when the French physicists finally observed its decay. WebBismuth is a soft, silvery metal with a bright, shiny surface and a yellowish or pinkish tinge. The metal breaks easily and cannot be fabricated (worked with) at room temperature. Its melting point is 271°C (520°F) and its boiling point is 1,560°C (2,480°F). Its density is 9.78 grams per cubic centimeter.
