KnowraBohr radiusLinked fromLinked fromThe 7 pages that link to Bohr radius, each with the reason it gives.All 7Broader topic 2Related 2Compared with 3Bohr modelBroader topic: It gives the scale of the model’s smallest hydrogen orbit.Compton wavelengthCompared with: It describes atomic binding and is far larger than the electron’s Compton wavelength.Classical electron radiusCompared with: It describes an atomic state, not the electron’s electromagnetic self-energy.Hydrogen-like atomRelated: It sets the orbital-size scale, modified by nuclear charge and reduced mass.Electron massRelated: It depends directly on electron mass and sets the scale of atomic size.Atomic unitsBroader topic: It is the atomic unit of length implied by the chosen constants.ÅngströmCompared with: This atomic-scale constant is a physical length, unlike the defined unit ångström.
