Arrange the following elements in the order of increasing atomic size Cl, S, P, Ar
A.Ar, Cl, S, P
B.Cl, S, P, Ar✓ Correct
C.S, Cl, P, Ar
D.Ar, P, S, Cl
Explanation
Along the period, size decrease but it is valid from group 1 to group 17. As group 18 have complete octet and stable, and they have van der Waals radius so have large size. So order is Cl S P Ar
