QJEEM19Ch97bc: JEE Main 2019 Chemistry - Class 11 JEEM19Ch97bc Solution: The correct order of the atomic radii of C, Cs, Al, and S is :
The correct order of the atomic radii of C, Cs, Al, and S is :
Multiple Choice Options
- A S < C < Al < Cs
- B S < C < Cs < Al
- C C < S < Al < Cs
- D C < S < Cs < Al
Step-by-Step Verified Solution
Atomic radii increase by moving down the group and decrease across a period.
Hence, the correct order of atomic radii is : C < S < Al < Cs.
Hence, the correct order of atomic radii is : C < S < Al < Cs.
