Carbon

Carbon is the sixth element and one of the most common and important elements. It forms two nearby bonds, and thus bonds readily with elements such as itself, hydrogen, vanadium, yttrium, iodine, fluorine, and so on.

Carbon is highly reactive in pure form. Carbon has three stable forms at standard conditions: gaseous C2 (dicarbane, the most common and least reactive), crystalline solid C(n) chains, and gaseous C3 (carzone, the least common and most reactive). Bond angle strain is minimized in solid carbon, but dicarbane is more stable by virtue of being a far smaller molecule with less mechanical strain.

Carbon readily bonds with hydrogen, and is present in most hydranic compounds, including the simplest, mydrane (C2H). Functional groups containing carbon include the carbon cap of a hykane chain, carrhydes, hyklanes, percarbanes, cyklanes, limines, and (iso)fluorolimines, among others.

Carbon also forms common compounds with several other elements, prominently yttrium to form the toxin carbon limide, PYC, phosphorus to form carlanes such as mycarlane (P2C2), vanadium to form vanadac (VC), fluorine to form carbon fluorolimide and carbon isofluorolimide (both PFC), and iodine to form some hykenes such as mydrene (C2I2).

Dicarbane (C2) reacts readily at higher temperatures with most hydranics and a variety of other compounds via the burning reaction, which breaks a double bond (such as a H=H bond) and caps both ends with a carbon.
