What are the stable isotopes of carbon?

Isotopes are substances that share the same atomic number but have distinct mass numbers. Many other substances can also be found in isotopic form in nature. The change in the number of protons and neutrons is what causes the difference in the mass number of isotopes.

The chemicals which have the same atomic number but are found to be different mass numbers are known as isotopes.

The carbon-$12$ and carbon-$13$ are the stable isotopes because they won’t undergo any decay process to get stability.

- The question asks you to list the stable carbon isotopes.
- The atomic number of carbon is six, and it is part of the IV A group's p-block.
- The carbon atom has six electrons.
Carbon has three stable isotopes: carbon-12, carbon-13, and carbon-14.
- The atomic masses of carbon-12, carbon-13, and carbon-14 are 12, 13, and 14, respectively.
- However, they brought up the stable isotopes of carbon in their query.
- The unstable carbon isotope carbon-14 will continually renew in nature because it is an unstable isotope of carbon.

Hence option (B) is correct.
