Carbon: The sixth element of the periodic table

Overview

Carbon is the sixth element in the periodic table. Its stable isotopes include 12C, the nucleus of which contains six protons and six neutrons, and 13C, which contains six protons and seven neutrons. Carbon is the fourth most abundant element in the solar atmosphere, after hydrogen, helium, and oxygen. This predominance is largely due to the autocatalytic role of carbon in the stellar nucleosynthesis of elements higher than hydrogen via proton addition (Bethe 1939):
$$ \begin{array}{c}{}^{12}\mathrm{C}+\mathrm{H}{\to}^{13}\mathrm{N}+\gamma \\ {}{}^{13}\mathrm{N}{\to}^{13}\mathrm{C}+{\mathrm{e}}^{+}\\ {}{}^{13}\mathrm{C}+\mathrm{H}{\to}^{14}\mathrm{N}+\gamma \\ {}{}^{14}\mathrm{N}+\mathrm{H}{\to}^{15}\mathrm{O}+\gamma \\ {}{}^{15}\mathrm{O}{\to}^{15}\mathrm{N}+{\mathrm{e}}^{+}\\ {}{}^{15}\mathrm{N}+\mathrm{H}{\to}^{12}\mathrm{C}{+}^4\mathrm{He}\end{array} $$
