In the atomic spectrum of neon each line represents:
Correct answer: C. A photon with specific energy
- A. A different atom
- B. A different element
- C. A photon with specific energy
- D. An atom splitting
Explanation
Each line in an atomic spectrum is produced by photons of one particular energy emitted when electrons fall between two definite energy levels. All the lines come from the same element, neon, so they cannot represent different atoms or elements, and no atom splits in the process.

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.
