Question

define penetrating power? what is the order of penetrating power of following
1s 2s 5s 3d

Answer 1

More is the penetration of orbitals more will be the ionization enthalpy.The s -orbital is more close to Nucleus than the p- orbital of the same Orbit so it is difficult to remove electron from s-orbital.
So the order of penetration power or ionization enthalpyies is s>p>d>f.
Ionization enthalpy directly proportional to penetration power.
