Among main group (groups 1, 2, 13–17) alkyl derivatives QR n, where n is the standard bonding number for Q (see lambda convention), the group 14 derivatives QR 4 are notable in being electron-precise: they are neither electron-deficient (having fewer electrons than an octet and tending to be Lewis acidic at Q and usually existing as ...

Carbon-14 can also be produced by other neutron reactions, including in particular 13 C(n,γ) 14 C and 17 O(n,α) 14 C with thermal neutrons, and 15 N(n,d) 14 C and 16 O(n, 3 He) 14 C with fast neutrons. [28] The most notable routes for 14 C production by thermal neutron irradiation of targets (e.g., in a nuclear reactor) are summarized in the ...
The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and transition metal carbonyl complexes. The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil, and methane clathrates.
Examples include carbon-14, nitrogen-15, and oxygen-16 in the table above. Isobars are nuclides with the same number of nucleons (i.e. mass number) but different numbers of protons and neutrons. Isobars neighbor each other diagonally from lower-left to upper-right. Examples include carbon-14, nitrogen-14, and oxygen-14 in the table above.
The total number of unique species, including distinct ionization states, is indicated in each section header. Most of the molecules detected so far are organic. The only detected inorganic molecule with five or more atoms is SiH 4. [14] Molecules larger than that all have at least one carbon atom, with no N−N or O−O bonds. [14]
Nitrogen-14 is one of the very few stable nuclides with both an odd number of protons and of neutrons (seven each) and is the only one to make up a majority of its element. Each proton or neutron contributes a nuclear spin of plus or minus spin 1/2 , giving the nucleus a total magnetic spin of one.
The number of protons (Z column) and number of neutrons (N column). energy column The column labeled "energy" denotes the energy equivalent of the mass of a neutron minus the mass per nucleon of this nuclide (so all nuclides get a positive value) in MeV, formally: m n − m nuclide / A, where A = Z + N is the mass number. Note that this means ...
