Phrase: Sommerfeld model | Statement: [Drude model, extendedBy, Sommerfeld model]

Target entity: Sommerfeld model
Context triple: [Drude model, extendedBy, Sommerfeld model]

• A. Sommerfeld fine-structure formula
  The Sommerfeld fine-structure formula is a relativistic extension of the Bohr model that accurately predicts the fine-structure energy levels of the hydrogen atom.
• B. Sommerfeld quantization rules chosen
  Sommerfeld quantization rules are an early quantum theory refinement of Bohr’s model that quantize electron motion in elliptical orbits using action integrals, helping to explain fine-structure details in atomic spectra.
• C. Bohr model of the atom
  The Bohr model of the atom is an early quantum theory in which electrons orbit the nucleus in discrete, quantized energy levels, explaining atomic spectra such as that of hydrogen.
• D. Bohr
  Bohr is a prominent Danish surname most famously associated with physicist Niels Bohr and mathematician Harald Bohr.
• E. Rydberg–Ritz combination principle
  The Rydberg–Ritz combination principle is a rule in atomic spectroscopy stating that the frequencies (or wavenumbers) of spectral lines can be expressed as differences between terms in a series, enabling systematic prediction and classification of atomic spectra.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
