Hydrogen atom does not emit X-rays because
Correct answer: A. its energy levels are too close to each other
- A. its energy levels are too close to each other
- B. its energy levels are too far apart
- C. it has a very small mass
- D. it has a single electron
Explanation
A is the right option Here's why: The X-ray emission typically involves transitions between energy levels that are relatively far apart. In hydrogen, the energy levels are closely spaced in the ultraviolet region, but to emit X-rays, transitions between much higher energy levels would be necessary.

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.
