Answer

Brief Explanations:

Isotopes of an element have the same number of protons (hence same atomic number) but different numbers of neutrons, resulting in different mass - numbers. Some isotopes are stable while others are radioactive.

Answer:

  • Isotopes have the same atomic number.
  • Isotopes are stable or radioactive.
  • Isotopes have different mass numbers.
