# Probability density of electron orbital

Why the probability of density is higher in the area that is closer to the nucleus? I'm a high school student. I don't know much about wave functions.

This is the spoor of classical behaviour left in quantum physics: although the electron can, in an orbital, be in regions that it classically cannot be, it is most likely to be in regions that it would be in classically. You will find that your statement is only true for the ground state: in raised eigenstates the probability density is maximal in regions some distance from the nucleus. –  WetSavannaAnimal aka Rod Vance Feb 25 at 2:43
Here's a simple derivation that I like. Classically, we can still have our concept of force and energy but it needs to be supplemented by the uncertainty principle. feynmanlectures.caltech.edu/III_02.html#Ch2-S4 –  RdErdwien Feb 25 at 2:50
still, why in classical sense it works? Because of the attraction force and colomb force? –  user40003 Feb 25 at 3:03
@WetSavannaAnimalakaRodVance in fact, in S states the probability density is still at maximum close to nucleus. –  Ruslan Feb 27 at 17:56
