This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 6 C carbon (graphite) use ...
At standard pressure, carbon, the lightest carbon group element, sublimes at 3825 °C. Silicon's boiling point is 3265 °C, germanium's is 2833 °C, tin's is 2602 °C, and lead's is 1749 °C. Flerovium is predicted to boil at −60 °C. [11] [12] The melting points of the carbon group elements have roughly the same trend as their boiling points ...
Carbon is the sixth element, with a ground-state electron configuration of 1s 2 2s 2 2p 2, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements.
For a metal, zinc has relatively low melting (419.5 °C) and boiling point (907 °C). [29] The melting point is the lowest of all the d-block metals aside from mercury and cadmium ; for this reason among others, zinc, cadmium, and mercury are often not considered to be transition metals like the rest of the d-block metals.
[24] [f] Its boiling point of 1749 °C (3180 °F) [33] is the lowest among the carbon-group elements. The electrical resistivity of lead at 20 °C is 192 nanoohm -meters, almost an order of magnitude higher than those of other industrial metals (copper at 15.43 nΩ·m ; gold 20.51 nΩ·m ; and aluminium at 24.15 nΩ·m ).

The boiling point (82 K) and melting point (68 K) are very similar to those of N 2 (77 K and 63 K, respectively). The bond-dissociation energy of 1072 kJ/mol is stronger than that of N 2 (942 kJ/mol) and represents the strongest chemical bond known.
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
