Question

There are three isotopes of carbon which are named as C-12,C-13 and C-14 out of which C-12 is the most abundant isotopes. In the given structures of 3 isotopes, what will be the composition of the nucleus?

Answer 1

Answer:

C-12 because the relative atomic mass of carbon is 12.011. it is close to 12

C-13 and C-14 are practically negligible when contributing to the relative atomic mass of carbon.

All three have six protons, but their neutron numbers - 6, 7, and 8, respectively but  all differ
