In chemistry, carbon (TR:219) (LH:20) (TL:239), symbol C, is the 6th element of the periodic table, which is an atom comprised of 6 protons, 6 neutrons, and 6 electrons, with an electron configuration of: [He] 2s2 2p2. The protons and neutrons are confined to the nucleus. The electrons surround the nucleus in two orbitals, an inner s-orbital, wherein two electrons move, and an outer p-orbital, wherein four electrons move. Combined, the s-orbital and p-orbital form four sp3 hybridized orbitals, arranged in a tetrahedral geometry, which favors the formation of four bonds with other elements, wherein the octet rule is satisfied.
The following shows the basic geometrical structure of carbon:
The following is an early estimate of the percent carbon in humans:
- “The human body contains carbon 13.5%, hydrogen 9.1%, oxygen 72%, nitrogen 2.5%, phosphorus 1.15%, sodium 0.1 %, calcium 1.3%, magnesium 0.001%, iron 0.01%, and traces of silicon and fluorine.”

- “Why should a group of simple, stable compounds of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), 'struggle' for billions of years to organize themselves into a professor of chemistry? What's the motive?”
