Outlined below, but beware of atomic radii trend.
Explanation:
a. atomic radii
Increases down a group (top to bottom). Decreases across a period (left to right).
b. first ionization energy
Increases across a period (left to right). Decreases down a group.
c. electron affinity
Increases across a period. Decreases down a group.
d. ionic radii
Increases down a group. Decreases across a period until non metals, then increases.
Increases across a period. Decreases down a group.
