A little perspective

The ground-state binding energy of Hydrogen atom ground-state binding energy is about 1.36 times the energy of 10 electronvolts.

Measurements, assumptions & sources +

10 electronvolts

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

NIST — SI conversion factors

Hydrogen atom ground-state binding energy

The magnitude of the hydrogen ground-state binding energy is approximately 13.598 eV, or 2.1799 × 10⁻¹⁸ J. It is the energy required to ionise ground-state hydrogen, not a classical stored-energy shell.

NIST — Atomic spectra database ionization energies

The marked ground-state binding energy is calibrated. Unmeasured illustration details are representative.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Hydrogen atom ground-state binding energy is labelled recommended value; treat the displayed value as a comparison anchor rather than false precision.
