The correct order of atomic radius of Li, Na, Be and O is
- A. Na \gt Li \gt Be \gt O ✓
- B. Na \gt Be \gt Li \gt O
- C. Be \gt Li \gt Na \gt O
- D. O \gt Be \gt Li \gt Na
Correct Answer: A. Na \gt Li \gt Be \gt O
Explanation
Atomic radius increases as you move down a group (Na \gt Li) and decreases as you move left to right across a period (Li \gt Be \gt O). Thus, Sodium has the largest radius, followed by Lithium, Beryllium, and Oxygen.
