Why does the atomic size generally increase down a group on the periodic table?
This occurs becasue the number of energy levels increase, which makes the electrons extend further from the nucleus.

Why does ionization increase across a period on the Periodic Table?
Moving across the Periodic Table more elctrons are being added within the the same energy level. This makes the charge between electrons and protons stronger.
