4. Electrons move from high energy states to lower energy states.

Bright-line emission spectra are produced for atoms in hot gaseous state when electrons move excitedly from higher energy levels to lower energy levels and emit discrete quantities of energies while they transition. This emitted energy forms bright and discrete lines in the spectra, forming a characteristic bright-line spectrum for each atom.
