Answer:

Different mass, same atomic number

Explanation:

  • Elements are made of similar atoms, however the atoms may have different number of neutrons but the same number of protons in their nucleus.
  • Such atoms that have equal number of protons but different number of neutrons are known as isotopes.
  • Difference in the number of neutrons makes isotopes to have different mass numbers.
  • Atomic number is the number of protons in the nucleus of an atom, therefore, isotopes have the same atomic number.
