In page Carbon:

"

Chemically, carbon is notable for its ability to form stable chemical bonds with many elements, particularly with other carbon atoms, and is capable of forming multiple stable covalent bonds with suitable multivalent atoms. Carbon is a component element in the large majority of all chemical compounds, with about two hundred million examples having been described in the published chemical literature.[citation needed] Carbon also has the highest sublimation point of all elements. At atmospheric pressure it has no melting point, as its triple point is at 10.8 ± 0.2 megapascals (106.6 ± 2.0 atm; 1,566 ± 29 psi) and 4,600 ± 300 K (4,330 ± 300 °C; 7,820 ± 540 °F),[3][4] so it sublimes at about 3,900 K (3,630 °C; 6,560 °F).[5][6]
