WebIn fact there are three isotopes of carbon atoms - all three react the same way in chemical reactions–the only chemical difference between them is that they have slightly different masses. The heaviest is carbon-14 (which, in the scientific world, is written as 14 C), followed by carbon-13 ( 13 C), and the lightest, most common carbon-12 ( 12 C).

WebCarbon has two stable isotopes ( 12 C and 13 C) of ∼ 98.89% and ∼ 1.11% abundance, respectively. Carbon compounds are exchanged between the oceans, atmosphere, biosphere and lithosphere. Significant isotope ratio variations exist within these groups due to both kinetic and equilibrium isotope effects. WebIsotopes do differ in their stability. Carbon-12 (12 C) is the most abundant of the carbon isotopes, accounting for 98.89% of carbon on Earth. Carbon-14 (14 C) is unstable and only occurs in trace amounts. Unstable isotopes most commonly emit alpha particles (He 2+) and electrons. Neutrons, protons, and positrons can also be emitted and ... overcast by behr
