carbon - 12 and carbon - 13 are isotopes of carbon. which of the following statements is correct?\nthey both have seven protons in the nucleus.\nthey both have the same mass number.\nthey both have seven neutrons in the nucleus.\nthey both have the same atomic number.

Answer

Answer:

They both have the same atomic number.

Brief Explanation:

Isotopes have same atomic number (number of protons), different mass - numbers due to different neutron numbers. Carbon - 12 and carbon - 13 are carbon isotopes, so they have same atomic number (6), different mass numbers (12 and 13).
