Atomic Structure - Isotopes and electrons

Isotopes

• 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…
