Explain the production of an emission spectrum in terms of the energy states of an electron.

what does that mean someone help me please.

is this a good answer?

When the electrons in the element are excited they jump to higher energy level and as the electrons fall back down it leave the excited state energy which is re-emitted, the wavelength of which is the emission spectrum.
I like part of it. I have bolded the change I would make. Feel free to change it to your writing style if you wish. By the way, the emitted spectrum MAY be in the visible spectrum but it may also be in the ultraviolet, infrared, x-ray region, etc etc.

When the electrons in the element are excited they jump to higher energy level and as the electrons fall back down to the lower level they emit the difference in energy between the excited state and the lower state. That emitted energy is the emission spectrum. it leave the excited state energy which is re-emitted, the wavelength of which is the emission spectrum.
