QNEET-2024-Ch-107: NEET 2024 Chemistry - Class 11 NEET-2024-Ch-107 Solution: The correct decreasing order of atomic radii (pm) of Li Be B…
The correct decreasing order of atomic radii (pm) of Li Be B and C is Be>Li>B>C Li>Be>B>C C>B>Be>Li Li>C>Be>B
Multiple Choice Options
- A \mathrm{Be}>\mathrm{Li}>\mathrm{B}>\mathrm{C} Be > Li > B > C
- B \mathrm{Li}>\mathrm{Be}>\mathrm{B}>\mathrm{C} Li > Be > B > C
- C \mathrm{C}>\mathrm{B}>\mathrm{Be}>\mathrm{Li} C > B > Be > Li
- D \mathrm{Li}>\mathrm{C}>\mathrm{Be}>\mathrm{B} Li > C > Be > B
Step-by-Step Verified Solution
As the atomic number in a period increases, the effective nuclear charge also increases hence, atomic radii along the period decreases.
Correct order of atomic radii
Li > Be > B > C
