JEE MAIN - Chemistry (2019 - 11th January Morning Slot - No. 4)
The correct order of the atomic radii of C, Cs, Al, and S is :
S < C < Al < Cs
S < C < Cs < Al
C < S < Al < Cs
C < S < Cs < Al
Explanation
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.
