Correct answer: A. Atomic weights
- A. Atomic weights
- B. Atomic numbers
- C. Number of protons
- D. Number of electrons
Explanation
Isotopes have the same atomic number, proton count, and, for neutral atoms, electron count. Their neutron counts differ, so their mass numbers or atomic weights are different.
