KnowraHydrogen-like atomLinked fromLinked fromThe 8 pages that link to Hydrogen-like atom, each with the reason it gives.All 8Broader topic 3Narrower topic 4Compared with 1Hydrogen atomNarrower topic: This broader family follows similar equations but has greater nuclear charge than hydrogen.Fine structureBroader topic: Its spectrum provides the clearest setting for calculating the leading fine-structure corrections.Rydberg formulaBroader topic: Replacing hydrogen’s nuclear charge extends the formula to one-electron ions.Principal quantum numberNarrower topic: The same principal-level pattern applies beyond hydrogen, with energies also depending on nuclear charge.Rydberg constantNarrower topic: The constant's characteristic scale extends from hydrogen to one-electron ions, with charge and mass adjustments.Bohr radiusBroader topic: Its orbital length scale is the Bohr radius divided by Z, with reduced-mass correction.Rydberg atomNarrower topic: Its simple Coulomb potential explains many Rydberg energy levels.Exotic atomCompared with: Its ordinary electron provides the baseline for comparing exotic-particle energy shifts.
