WebA 2s orbital is similar to a 1s orbital, but it has sphere of electron density inside the outer sphere, like one tennis ball inside another. There is a surface between the two balls where there is zero probability of finding an electron. We call this surface a node or a nodal surface. A 3s orbital is even larger, and it has three nodes. p ORBITALS Web1s < 2s = 2p < 3s = 3p = 3d < 4s = 4p = 4d = 4f Factors affecting the Orbital Energy The s orbital electron will be more tightly bound to the nucleus as compared to the p orbital electron, which is more tightly bound in regard to a d orbital electron for a given value of the principal quantum number. WebMay 4, 2015 · 1 Answer. It would be the 3 s shell because less energy is required to bump it off course. Due to electron repulsion and the shielding effect, the e − in the 3 s is more prone to get dislodged. And of course because of this, it will have a higher velocity when it gets bumped off. Another concept to note: e − will have more energy at higher ... chinese food in maxton nc
