How is the atomic emission spectrum of an element produced?

Atomic emission spectra are produced when excited electrons return to the ground state. The emitted light of electrons corresponds to energies of the specific electrons.

hope it helps you ✌

When an electron in an atom returns from an excited state to a lower energy state.

Explanation:

Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state.

Emission spectrum has characteristic energy proportional to the frequency of the light.

Each element's emission spectrum is unique.
