Answer:
The answer to your question is:
atomic number (Z): 6
mass number (A) : 13
Explanation:
Carbon has an atomic number of 6 and a mass number of 12,
Mass number = # protons + # neutrons
12 = 6 + # neutrons
#neutrons = 12 - 6 = 6
For the carbon isotope the atomic number does not change is still 6
13 = 6 + # neutrons
# neutrons = 13 - 6
# neutrons = 7
