Study Notes
Atomic Radius Concepts
- Smallest atomic radius element among choices: Nitrogen (N)
- Largest atomic radius element in the group: Sodium (Na), compared to argon, phosphorus, aluminum, and magnesium
- Largest atomic radius overall in provided options: Barium (Ba)
Trends in Atomic Radius
- Atomic radius decreases as you move from left to right across the periodic table due to increased nuclear charge; more protons attract electrons, pulling them closer to the nucleus.
- Atomic radius increases when moving from top to bottom in a group, as additional electron shells are added, leading to a larger size.
