Size of the d orbitals for Si, P, S and Cl follow the order :
Si > P > S > Cl
Si, P, S, Cl lie in period 3 with nuclear charge increasing from Si to Cl
Higher effective nuclear charge contracts the vacant 3d orbitals
So the 3d orbitals are most diffuse for Si and most contracted for Cl
Size order: Si > P > S > Cl
Hence, Si > P > S > Cl.
