Complete the sentences to identify the trend in first ionization energies as one proceeds down the group 7A elements and explain how this trend relates to the variation in atomic radii.

Complete the following sentences using this word bank:

a. increase
b. decrease
c. greater
d. smaller

1. Moving from F to I in group 7A, first ionization energies
2.Moving from F to I in group 7A, atomic radii
3. The relationship between atomic radii and first ionization energy going down a column is best explained by the fact that the greater the atomic radius, the the electrostatic attraction of an outer electron for the nucleus and the the ionization energy of the element.
