Which one is different for the neutral atoms of the isotopes of an element ?
Correct answer: D. Atomic weights
- A. Number of electrons
- B. Atomic numbers
- C. Number of protons
- D. Atomic weights
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.
