Carbon (6 C) has 14 known isotopes, from 8 C to 20 C as well as 22 C, of which 12 C and 13 C are stable. The longest-lived radioisotope is 14 C, with a half-life of 5.70(3) × 10 3 years. This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reaction 14 N + n → 14 C + 1 H. The most ...
15 isotopes of the element carbon are known - 2 of which are stable (12 C, 13 C), the others occur as unstable natural decomposition products (14 C) on or were artificially generated. The carbon radioisotope with the longest half-life (5700 years) is C-14, which also occurs in traces in nature.
Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.
Color-coded pie charts in each element cell display the stable isotopes and the relatively long-lived radioactive isotopes having characteristic terrestrial isotopic compositions that determine the standard atomic weight of each element.
Useful stable isotopes include boron-10 (10B) used in boron neutron capture therapy for treating brain tumors and carbon-13 and carbon-12 (13C/12C) or oxy-gen-18 and oxygen-16 (18O/16O) to detect performance-enhancing drug use in sports, authenticity of foods, effects of climate change, and origins of contaminants in the environment.
Carbon has as many as 15 isotopes. They all have an atomic number of 6, but differ in their atomic masses. Though they all have the same number of protons (6), each one differs in the number of neutrons, in the nucleus. Most of them are radioactive.
Isotopes are atoms that have the same number atomic number, but different mass numbers due to a change in the number of neutrons. The three isotopes of carbon can be referred to as carbon-12 (126 C 6 12 C), carbon-13 (136 C 6 13 C), and carbon-14 (146 C 6 14 C) refers to the nucleus of a given isotope of an element.
