Step 1Let's solve this step by step by analyzing the trends in atomic and ionic radii.
Step 2: Understanding Atomic and Ionic Radii
- Atomic radius is the distance from the nucleus to the outermost electron - Ionic radius depends on the number of electrons and the nuclear charge - Gaining or losing electrons affects the size of an atom/ion
Final Answer
Option A is correct. \mathrm{N}^{3 -} > \mathrm{N} represents the correct trend in radii size.
