Question:
Match the following:
Element List - II Atomic Radius (in pm) A. Na I. 152 B. Li II. 99 C. Cl III. 64 D. F IV. 186
Match the following:
| Element | List - II | Atomic Radius (in pm) |
| A. Na | I. | 152 |
| B. Li | II. | 99 |
| C. Cl | III. | 64 |
| D. F | IV. | 186 |
Show Hint
Atomic radii decrease across a period and increase down a group in the periodic table.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
From the periodic table, we know the atomic radii of the elements as:
- Na (Sodium) has an atomic radius of 186 pm (IV).
- Li (Lithium) has an atomic radius of 99 pm (I).
- Cl (Chlorine) has an atomic radius of 152 pm (II).
- F (Fluorine) has an atomic radius of 64 pm (III).
Thus, the correct matching is: \[ \text{A - IV, B - I, C - II, D - III} \]
