Question and answer
Q: Describe the cause of atomic emission spectrum of an element. How is the change in electron energy related to the frequency of light emitted in atomic transitions?
A: Cause of atomic emission spectrum of an element- The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom's electrons making a transition from a high energy [ state to a lower energy state. Change in electron energy is related to the frequency of light emitted in atomic transitions The energy of the
emitted photon is equal to the energy difference between the two states. There are many possible electron transitions for each atom, and each transition has a specific energy difference. This collection of different transitions, leading to different radiated wavelengths, make up an emission spectrum. ]
