Answer:
Explanation:
Nucleons are the particles that are in the nucleus of the atom, i.e. protons and neutrons.
So, the nucleon number is the number of protons and neutrons.
Other name for nucleon number is mass number, and it is represented by the letter A:
nucleon number = mass number = A = protons + neutrons.
Carbon-14 is the particular name, indicating the mass number, of the isotope of carbon with mass number 14.
So, the nucleon number of carbon-14 is indicated in its name, and it is 14.
The name carbon-14 identifies completely the isotope because, the atomic number of carbon is the same for every atom (isotope) of carbon:
