Quantum Electron Question
« on: October 25, 2007, 03:08:01 PM »
Explain why in a many electron atom, a 3s-electron is bound more strongly than a 3p-election.

Look up orbital shapes for s and p.

The s orbital retains perfect symmetry.

The electron in the 3s orbitals will experience more attraction from the nucleus. The 3s electrons will be shielding the 3p electrons from the nucleus' attraction. If you look at the ionization energy across the periodic table you will see that it decreases at that point. The 3s orbitals are the core electrons in this case, it will be a lot closer to the nucleus than the 3p electrons making the electrons in the 3p orbitals held more loosely. Not sure if I answered your question. Hope this help  :)
