Surely it is ""^14C?

#### Explanation:

YOu have not given us a list of istopes, but the isotopic distribution of carbon is given here..........

""^12C is about 98.9% abundant.........""^13C is approx. 1.1% abundant. This nucleus allows solution (and now solid-state) spectroscopy, and direct characterization of organic compounds...

There are trace quantities of the heavier isotope, ""^14C#....

How many neutrons does each isotope contain?
