Want this question answered?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
When an elctron is excited (has energy) it is extremely unstable, so it falls back to its previous energy level, and when it does this it releases energy, and this energy is viewed as wavelengths of light. So the color depends on the amount of energy the atom releases when it falls back to its lower energy level.
First, in order for an electron in an atom to change energy levels, there must be a place for it in the new energy levels. Quantum Mechanics puts very strict rules on how many electrons can be in the same energy level. Assuming there is a place for it, then it is very likely to move into a lower energy level. It is not possible for it to move into a higher energy level unless something from the outside comes in and knocks it up. There is no way to predict when an electron will drop down into a lower energy level. When something like a photon comes in from the outside and knocks the electron into a higher level, it usually drops back down pretty quickly, but not necessarily.

The electron has several possible energy levels. One of the lines corresponds to a transition from level 2 to level 1, another from level 3 to level 1, another from level 4 to level 1, another from level 3 to level 2, etc.
when heat is provided to an electron it jumps from a lower energy level to a higher energy level.but when heat is not provided it will come back to its own level.

When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.

Energy is either absorbed or released. If the electron goes from a high energy orbital to a lower energy one, a photon is emitted. When a photon is absorbed, the electron goes from low energy to high.
The electron gains energy.
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
Electrons are attracted to the nucleus of the atom of which they are a part; this is because of the electrostatic force between the negatively charged electron and the positively charged nucleus. Therefore it takes energy in order to pull an electron farther away from the nucleus and to enable it to remain at a greater distance. This is exactly the same phenomenon as raising a heavy object such as, let us say, a bowling ball, to a greater elevation. It takes energy to do it, since you have to overcome the force of gravity.
