Question:
The two stable isotopes of carbon present in the naturally occurring carbon are
The two stable isotopes of carbon present in the naturally occurring carbon are
Show Hint
$^{12}$C and $^{13}$C are stable; $^{14}$C is radioactive.
Stable isotopes = no radioactive decay.

- $^{12}$C and $^{14}$C
- $^{12}$C and $^{13}$C
- $^{12}$C and $^{15}$C
- $^{14}$C and $^{12}$C
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Carbon naturally exists as two stable isotopes:
\[
^{12}\text{C} \quad (\text{~98.9%}) \quad \text{and} \quad ^{13}\text{C} \quad (\text{~1.1%})
\]
$^{14}$C is a radioactive isotope with a half-life of about 5730 years and is used in radiocarbon dating, not considered stable.
