WebSep 22, 2024 · Atomic Emission Spectra. Electrons in atoms normally occupy the lowest energy states possible. Such an atom is said to be in the ground state. However, electrons can be excited to high energy states when they absorb excess energy. The excess energy can be provided by heat, light, or electrical discharge. The electrons then return to lower ... WebTable 1-2. Photon energies, in electron volts, of principal K-, L-, and M-shell emission lines.
