Why are s orbitals more “penetrating” than p orbitals?

WebSee if your textbook has a section covering the concepts of electron shielding and penetration. There is a subtle balance of the two going on that makes 4s fill in before 3d, and that balance gets tipped when you move over to the transition metals. For them, 3d always fills in before 4s (if you're building the atom by adding in electrons one at ... Web• The degree of penetration is related to the orbital’s radial distribution function. – In particular, the distance the maxima of the function are from the nucleus Shielding and Penetration Penetration and Shielding • The radial distribution function shows that the 2s orbital penetrates more deeply into the 1s orbital than does the 2p.
