Boundary & unit check (Bohr Model Generator)

When solving for 'bohr model generator', verify that Nuclear charge Z, Initial principal level, Final principal level use consistent units and stay within the documented scope: E_n = −13.6 Z²/n² eV. Photon wavelength uses hc ≈ 1239.8419843320026 eV·nm. The nonrelativistic single-electron model ignores fine structure and many-electron screening. Equal levels report no transition and undefined photon wavelength. Numeric output uses up to 12 significant digits; floating-point rounding can occur.

Read the result in context: Equal levels mean zero transition energy. The result marks the wavelength as undefined rather than dividing by zero. The model is for an ideal single-electron hydrogen-like ion.

How to Read and Verify the Bohr Model Calculator Output

The output panel reports the exact result derived from Nuclear charge Z, Initial principal level, Final principal level alongside any unit or formatting notes.

Every calculation follows the rule: Calculate an ideal hydrogen-like energy change and photon wavelength between two Bohr levels. Because JavaScript uses IEEE 754 double-precision floating-point arithmetic, numeric outputs display up to 12 significant digits where applicable.

Always cross-check the displayed result against the scope note (E_n = −13.6 Z²/n² eV. Photon wavelength uses hc ≈ 1239.8419843320026 eV·nm. The nonrelativistic single-electron model ignores fine structure and many-electron screening. Equal levels report no transition and undefined photon wavelength. Numeric output uses up to 12 significant digits; floating-point rounding can occur) before applying the value to production specifications, financial models, or lab records.
