Question

the emission spectra of several elements found on the sun are shown. explain why each element has a unique emission spectrum.

Explanation:

Each element has a unique emission spectrum because electrons in different elements occupy distinct energy levels. When electrons transition between these levels, they emit photons with specific energies (and thus wavelengths). Since the energy level structures vary among elements, the emitted wavelengths (and the resulting spectra) are unique.

Answer:

Each element has a unique emission spectrum due to its distinct electron energy - level structure. When electrons transition between these levels, they emit photons of specific energies (and wavelengths), which are characteristic of the element.
