Electron in s-orbital is closer to nucleus than electron in p-orbital and electron in p-orbital is closer to nucleus than electron in d-orbital and so on. So,more energy is requried to remove electron from s-orbital than electron in p-orbital in spite of both having same principal quantum number. Similarly, p orbital will require more energy than d-orbital. this is called penetrating effect.

Penetration effect means the closeness of electrons in an orbital to the nucleus.

Explanation:

  • In an atom, the electrons are distributed in different orbitals and they experience a force of attraction from the nucleus.
  • The inner electrons are more attracted to the nucleus as compared to the outer electrons due to their closeness to the nucleus.
  • The ability of an electron to get closer to the nucleus is called penetration and the effect is called penetration effect.
  • In a multi-electron system, the penetrating power of an electron depends upon the value of shell and sub-shell.
  • If the value of shell (n) is same, then the penetrating power of sub-shells is s > p > d > f.
  • If the values of both shell (n) and sub-shell (l) are different, then the penetrating power is given as:

        \[1s > 2s > 2p > 3s > 3p > 4s > 3d > 4p > 5s > 4d > 5p > 6s > 4f...\]
