#3 Why does fluorine have a higher ionization energy than iodine? (since they are both in the same group, think about what changes down the periods)
It has a smaller atomic radius (so the protons are pulling the electrons tighter)
It has a higher electronegativity value
#4 Why do elements in the same family have similar properties?
They have all even or all odd numbers of protons
They have the same numbers of valence electrons
