Carbon-12 and carbon-13 are stable.
The fact that carbon-14 is unstable, with a relatively short half-life (very short compared to the age of the Solar System) means that it must needs have been produced more recently than the creation of the Solar System.
Kasandra Hegmann
The existence of carbon-12, carbon-13, and carbon-14 is well-established. Carbon-12 is the most abundant and stable isotope of carbon, making up around 99% of all carbon atoms. Carbon-13 is a less abundant stable isotope, while carbon-14 is a radioactive isotope with a half-life of about 5730 years. The presence of these isotopes is crucial for various scientific fields, such as carbon dating and isotopic analysis.

How do you find the atomic weight on the periodic table?
On many Periodic Tables, the small number directly below the chemical symbol is the atomic mass. On mine, there is a small 12.011 under the large C for carbon. While most carbon is 12, there are naturally occurring carbon13 and carbon14, so this is an average mass of all naturally occurring isotopes, with the majority of isotopes being carbon12
What is carbon's atomic mass?
Carbon's atomic mass is ~12.0107. All of those decimals at the end tell us that there is more than one isotope of carbon. If you round the number, you will find the most common isotope of carbon. (Carbon12)IUPAC recommend in this case the expression atomic weight, not atomic mass.The atomic weight of carbon (IUPAC Table, 2009) is [12,0096; 12,0116]. This mean that the atomic weight is variable between the above mentioned limits, depending on the type of the sample.
When naming hydrocarbons what does the suffix yne indicate about the structure of the molecule?
The meaning is the existence of a triple bond in alkynes.
Define allotrophy and names the allotropes of carbon?
Allotrophy is the existence of two or more different physical forms of a chemical element. Soot, Diamond, and Charcoal are all allotropes of carbon.
What is the standard for atomic mass unit called?
One twelfth (1/12) the mass of a carbon-12 atom is one atomic mass unit (amu, or just u).

How many carbon atoms are present in a mole of carbon12?
6.023 x 1023

How many years would it take for the mass of a 1.00 g sample of carbon12 to be reduce to 0.125g?
It will take practically forever. Carbon-12 is not radioactive.
What would be an isotope of carbon12?
The 12 in Carbon-12 designates the isotope which has an atomic mass of 12. This is the most abundant isotope of carbon. Carbon has an atomic number of 6, therefore it has 6 protons. Carbon 12, therefore has 6 neutrons. Carbon 14 is another isotope of carbon, still having 6 protons, but has 8 neutrons, so it has an atomic mass of (6 + 8 = 14).
