Light.
The exciting of an electron takes in energy. The fall back to the ground state releases that energy as a photon. The photon is created by the return to the ground state.
Energy must be emitted for an electron to return to the ground state. This energy typically occurs in the form of a photon--a particle/wavelet of light. Flourescent bulbs, for example, conduct a current through a gas knocking electrons into higher, more exicted orbits. As the electrons decay into lower orbits, light is emitted, producing the flourescent glow.
Normally, yes. 'Ground state' refers to electrons that are unexcited (meaning not pushed to a higher energy level) by heat or electricity. So basically, yes, valence electrons are always at ground state. I mean, unless you're sending an electrical current through the substance.
they return to their original energy levels.

What form of energy emission accompanies the return of excited electrons to the ground state?
When the electrons absorb energy from a source, such as heat, they move to an excited state (farther from the atoms nucleus). They then release the energy in the form of light which produces the observed spectral lines of color. Once the energy is released, the electrons move back to a lower energy level (ground state).
They return to their ground state from an excited state induced by the electric field between the two ends of the light.
energy is given out. this is emitted in the form light ie each atom has its own characteristic emission spectra.

they return to their original energy levels.
heating a solution is adding energy to the atoms, specifically the electrons. the electrons on the lowest energy level (n=1) absorb this energy and move up to a higher energy level. However, electrons dont like to stay on these high energy levels so they release the energy they absorbed (emitting a specific amount of energy in the form of a wavelength and a frequency =light) and return to the ground state/lowest energy level.
The electron falling one or more energy shells will produce a photon of energy equal to the difference in energy actually two or more in different directions all adding to the energy
