Tungsten has the lowest coefficient of thermal expansion of any pure metal. The low thermal expansion and high melting point and tensile strength of tungsten originate from strong metallic bonds formed between tungsten atoms by the 5d electrons.
Melting point: 3695 K (3422 °C, 6192 °F)
Boiling point: 6203 K (5930 °C, 10706 °F)
Electrons per shell: 2, 8, 18, 32, 12, 2
Electron configuration: 4f14 5d4 6s2
