Question

The correct order of the atomic radii of $C,Cs,Al$ and $S$ is :

• A. $S<C<Al<Cs$
• B. $S<C<Cs<Al$
• C. $C<S<Cs<Al$
• D. $C<S<Al<Cs$

Answer 1

Answer: (D)

Atomic radii order : C < S < Al < Cs
Atomic radius of C : 170 pm
Atomic radius of S : 180 pm
Atomic radius of Al : 184 pm
Atomic radius of Cs : 300 pm
