1.	18. Correct order of atomic radius is :- (1) V > Ti(2) CI > S(3) Rb > CS(4) Ne > Be
Answer» Option (3)EXPLANATION: Atomic radius increases while MOVING down to the group in the periodic table. THEREFORE, size of RB > size of Cs. Atomic radius of element decreases while moving left to right in the periodic table.Hence, answer is verified.
