    nucleus
  9. this includes the number of protons and electrons also tell the location of the element
    atomic number
  10. is the decimal or atomic mass unit
    mass number
  11. the same number of protons but different mass number, the number of neutrons change (stable or unstable(radioactive))
    isotope
