Atomic Structure and Atomic Spectra (CH 13)

Atomic Structure and Atomic Spectra (CH 13). A hydrogenic atom is a one-electron atom or ion of general atomic number Z ; H, He + , Li 2+ ,… A many-electron atom is an atom or ion with more than one electron. The SWE can be solved exactly only for hydrogenic atoms.
