Carbon-14 is radioactive and decays into nitrogen-14, which is not radioactive. Atoms with the same number of neutrons are called isotones. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Isotope of carbon which has two extra neutrons. When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons). Complete the table writing their atomic number, mass number, number of protons, electr-ons and neutrons. C-14 therefore has 8 neutrons. Carbon-14 has the same atomic number and atomic mass as carbon-12 atomic number and thus number of neutrons as carbon-13 number of protons but more neutrons than carbon-12 O Oatomic mass as both carbon-12 and carbon-13 Submit Request Answer. Atoms that have the same number of protons and electrons, but different numbers of neutrons are called: Social security number. 1. The stable isotopes are carbon 12 and carbon 13.Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms. This is done via beta decay. Carbon 12 and Carbon 14 are isotopes of the carbon atom. Carbon-14, (14C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Terms in this set (2) Carbon 14. One example of this decay is carbon-14 (6 protons, 8 neutrons) that decays to nitrogen-14 (7 protons, 7 neutrons) with a half-life of about 5,730 years. talia0397. a. This is also the only carbon radioisotope found in nature—trace quantities are formed cosmogenically by the reaction 14 N + 1 n → 14 C + 1 H. The most stable artificial radioisotope is 11 C, which has a half-life of 20.364 minutes. check_circle Expert Solution.
