WebBy far the most common isotope of carbon is carbon-12 ( 12 C), which contains six neutrons in addition to its six protons. The next heaviest carbon isotope, carbon-13 ( 13 C), has seven neutrons. Both 12 C and 13 C are called stable isotopes since they do not decay into other forms or elements over time. WebSome elements, such as carbon, potassium, and uranium, have multiple naturally-occurring isotopes. Isotopes are defined first by their element and then by the sum of the protons and neutrons present. Carbon-12 (or 12 C) contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 amu (six protons and six neutrons). ray\u0027s thunder garageWeb18 aug. 2024 · Potassium has three isotopes.
