Big

Explanation:

The larger the atomic radii the further the electrons are from the positive charge of the nucleus. The further the electrons are from the positive charge the less pull or force of attraction there is between the positively charged nucleus and the negatively charged electrons. The less force of attraction on the electrons the easier it is to pull the electrons away from the nucleus. Hence the larger the radii the lower the ionization energy.
