Step 1I'll solve this problem by analyzing the periodic table trends for atomic radius.
Step 2: Understanding Atomic Radius Trends
Atomic radius varies systematically across the periodic table: - Down a group (column), atomic radius increases - Across a period (row), atomic radius generally decreases
Final Answer
Cs (Cesium) has the largest atomic radius in this periodic table.
