Hydrogen atom does not emit X-rays because
Correct answer: B. Its energy levels are too far apart
- A. Its energy levels are too close to each other
- B. Its energy levels are too far apart
- C. It is too small in size
- D. It has a single electron
Explanation
Its energy levels are too far apart - Correct: X-rays are produced when high-energy transitions occur, typically in atoms with many electrons. In hydrogen, the energy gaps are not large enough to emit X-rays.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
