Answer

Brief Explanations:

  1. Down a group, new electron - shells are added, increasing ionic radius.
  2. Across a period, effective nuclear charge increases, pulling electrons closer, decreasing ionic radius for cations.
  3. Anions have gained electrons, increasing electron - electron repulsion and size. When switching from cations to anions in a period, anions are larger due to extra electrons.

Answer:

  • Ionic radii tend to increase down a group.
  • Ionic radii tend to decrease across a period.
  • Anionic radii tend to increase across a period.
  • Cationic radii tend to decrease across a period.
  • Ionic radii increase when switching from cations to anions in a period.
