Can you tell me the order of screening effect ?? (shielding effect)

Either the increasing order or decreasing order ... !!

most screening effect = s orbital

s>p>d>f

the reson is that as we go from s to f the size of orbital increses(circumference type) and thus the nuclear forces get more space to pass or ovrcome the boundary of the orbitals. as s has very less space so the nulear forces gets sheilded their i.e less force able to go beyond s orbital.

please approve by clicking "YES" below

Can we see any exceptional behaviors in any on the element ??
