Solution:

The relative extent to which the various orbitals penetrate the electron clouds of other orbitals is . Electron will experience the greatest effective nuclear charge when in -orbital, then a -orbital and so on. Ionisation energy increases with an increase in penetration power and thus, the order of screening effect is .
