Other less known oxides include carbon suboxide (C 3 O 2) and mellitic anhydride (C 12 O 9). [5] There are also numerous unstable or elusive oxides, such as dicarbon monoxide (C 2 O), oxalic anhydride (C 2 O 4), and carbon trioxide (CO 3). There are several oxocarbon anions, negative ions that consist solely of oxygen and carbon.
There are 15 known isotopes of carbon and the shortest-lived of these is 8 C which decays through proton emission and has a half-life of 3.5 × 10 −21 s. [15] The exotic 19 C exhibits a nuclear halo, which means its radius is appreciably larger than would be expected if the nucleus were a sphere of constant density. [76]
Unsaturated hydrocarbons, which have one or more double or triple bonds between carbon atoms. Those with one or more double bonds are called alkenes. Those with one double bond have the formula C n H 2n (assuming non-cyclic structures). [1]: 628 Those containing triple bonds are called alkyne. Those with one triple bond have the formula C n H ...
[20] [21] The individual layers are called graphene. In each layer, each carbon atom is bonded to three other atoms forming a continuous layer of sp 2 bonded carbon hexagons, like a honeycomb lattice with a bond length of 0.142 nm, and the distance between planes is 0.335 nm. [22]
Carbon atoms bond readily to other carbon atoms; this allows the building of arbitrarily long macromolecules and polymers in a process known as catenation. [ 20 ] [ 21 ] [ 22 ] "What we normally think of as 'life' is based on chains of carbon atoms, with a few other atoms, such as nitrogen or phosphorus", per Stephen Hawking in a 2008 lecture ...
This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.
In some molecules, there is a difference between valence and oxidation state for a given atom. For example, in disulfur decafluoride molecule S 2 F 10, each sulfur atom has 6 valence bonds (5 single bonds with fluorine atoms and 1 single bond with the other sulfur atom). Thus, each sulfur atom is hexavalent or has valence 6, but has oxidation ...
