Bismuth is a chemical element with symbol Biand atomic number 83. Bismuth, a pentavalentpost-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenicand antimony. Elemental bismuth may occur naturally, although its sulfide and oxideform important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge Melting point 544.7 K (271.5 °C, 520.7 °F) Boiling point 1837 K (1564 °C, 2847 °F) Density (near r.t.) 9.78 g/cm3 when liquid (at m.p.) 10.05 g/cm3 Heat of fusion 11.30 kJ/mol Heat of vaporization 179 kJ/mol Molar heat capacity 25.52 J/(mol·K) MATERIAL SAFETY DATA SHEET
