  • All isotopes have the same number of electrons moving in the same amount of shells outside their nucleas
  • They have the same amount of protons (in the nucleas) and electrons (outside the nucleas)
  • Isotope atoms are always neutrally charged
  • The only thing that changes is the amount of nuetrons in different nucleas' of different atoms

One atom two isotopes

  • Chlorine has two different isotopes
    • They both have the same atomic number (17) 
      • This means they have the same amount of protons (both isotopes)
      • Same…
