Step 1
I'll solve this problem step by step, focusing on atomic structure and periodic trends.

Step 2
: Understand Atomic Radius Trends

The atomic radius depends on several factors, primarily: - Number of protons in the nucleus - Number of electron shells - Effective nuclear charge - Electron-proton attraction

Final Answer

F, because the attraction between protons and valence electrons is stronger.
