Greetings,(adsbygoogle = window.adsbygoogle || []).push({});

Can someone give a detailed explanation of why the expectation value of z coordinate in the ground state of hydrogen atom is zero due to parity symmetry? In addition how do you represent parity inversion in spherical coordinates and how do spherical harmonics behave under this inversion ( I found the formulas but I want the derivation part if applicable)? Any help is appreciated.

P.S: This came up in first order perturbation theory while discussing the Stark Effect.

Thanks
