5.

#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)

a)

It has a smaller atomic radius (so the protons are pulling the electrons tighter)

b)

It has a higher electronegativity value

#4 Why do elements in the same family have similar properties?

a)

They have all even or all odd numbers of protons

b)

They have the same numbers of valence electrons
