Question

What are periodic trends if ionic radii

Answer 1

Explan ionization energy, atomic radius, and electron affinityation:

Answer 2

This question most likely has answer choices. The possible answer choices are as followed:

• 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.

The answers are Ionic radii tend to increase down a group, Cationic radii tend to decrease across a period, and Ionic radii increase when switching from cations to anions in a period (1st, 4th, and 5th options).
