Carbon (6 C) has 14 known isotopes, from 8 C to 20 C as well as 22 C, of which only 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

Carbon-13 (13 C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth.

Isotopes are distinct nuclear species (or nuclides) of the same chemical element. They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), but different nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei.

C 14 is the radioactive isotope that is primarily used in radiocarbon dating. Using this technique, archaeologists can determine the age of carbon-containing materials which are up to 60,000 years old.

Both 12 C and 13 C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 ( 14 C) isotope contains eight neutrons in its nucleus. Unlike 12 C and 13 C, this isotope is unstable, or radioactive.

List, data and properties of all known isotopes of Carbon. 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.

Apr 10, 2025 · An isotope of any element can be uniquely represented as \({}_Z^{A}X\)where X is the atomic symbol of the element. The isotope of carbon that has 6 neutrons is therefore \(\ce{_6^{12}C}\) The subscript indicating the atomic number is actually redundant because the atomic symbol already uniquely specifies Z. Consequently, it is more often ...

Jan 1, 2018 · Isotopes are atoms with the same number of protons but different numbers of neutrons. Traditional nomenclature denotes isotopic species as AZ E, in which Z is the element’s atomic number (e.g., number of protons) and A is the …

Carbon has two stable (non-radioactive) isotopes. In nature, the 12 C isotope comprises 98.89% of all carbon and 13 C makes up the remaining 1.11%.

Nov 8, 2019 · Carbon isotopes are atomic nuclei with 6 protons plus several neutrons (between 2 and 16). Carbon has two stable, naturally occurring isotopes. The isotope 12C forms 98.93% of the Carbon on Earth, while 13C forms the remaining 1.07%.
