### Atomic Spectra Wave Model or Particle Model?

According to Atomic Spectra, are electrons acting more as a wave or a particle? Please explain.

Atomic spectroscopy is the analysis of electromagnetic radiation that is emitted or absorbed and corresponds to the spectral lines that we see. These lines as we talked about in class, are unique to every element and are a result of the particle characteristics of electrons. This is because spectral lines are formed as a result of electrons transitioning between energy levels, which suggests that electrons can only have discrete energy values. And with other experiments like the photoelectric effect, it was discovered that electromagnetic radiation is composed of particles called photons.

Atomic spectra shows that light has particle-like properties. Electrons in atoms and molecules absorb/emit discrete packets of energy. Spectral lines result from a transition between two energy levels, and the difference in energy is emitted as a photon.
