How do you know which elements have the larger atomic radius and lower ionization energy?

atomic radius decreases ACROSS a period, and increases DOWN a group.
ionization energy is the opposite. , it increases across a period, and decreases down a group.

In general, the closer an element is to the lower left of the chart, the larger is the radius & the lower is the ionization energy
