Answer

Brief Explanations:

Isotopes of an element have the same number of protons but different numbers of neutrons. They are identified by their mass number. Some isotopes are unstable (radioactive), while others are stable. Atomic number is the number of protons and is the same for all isotopes of an element, so it doesn't distinguish between them.

Answer:

  • Isotopes of the same element have the same number of protons.
  • Some isotopes are unstable.
  • Isotopes are identified by their mass number.
