  • What are Isotopes?
  • Isotopes are elements in the periodic table that have the same atomic number, but a different mass number.
  • Isotopes are...
  • 13 C6 12 C6
  • Whats the Difference?
  • The number of protons determine the Atomic Number in an element. The atomic number never changes. Only the number of neutrons can change.
  • Electrons and Protons need to have an equal amount. Electrons need to have a equal amount to make the element stable, not unstable and to have a neutral charge. They do not affect the atomic mass since they weigh much less than neutrons and protons.
