Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.

Do atoms in the excited state have more electrons than in the ground state?
Yes, because an atom in an excited state will normally give off energy and go to a less-excited state or to its ground state. Some atoms have long-lived excited states and are called "metastable".
How does an excited atom go back to it's ground state?
It must omit a photon of light to lower the excited electron to a lower state. It may require multiple emissions to lower one electron multiple steps or multiple emissions to lower multiple excited electrons. (Incidentally this is why we see a blue sky - excited O2 molecules are emitting blue photons to get back to a ground state)
When an atom is excited the electrons go up in energy level and then soon return to ground state emitting a photonif energy can not be related were physically does this photon come from?
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.
Can an electron stay in an excited state without outside energy?
No, It is due to the fact that without energy an electron can not go to excited state.
What is the definition of excited state electron?
An atom will go into an excited state when the electrons are given extra energy. Then after the electrons have been excited it will eventually go back to ground state producing a light as it returns to its normal state.

When does an electron go from the ground state to an excited state?
When the atom absorbs energy of the proper frequency/energy.
What must happen for an atom to go from an excited state to a ground state so color is seen?
An excited electron spontaneously drops back to its ground state, emitting a photon of light as it does so. <><><><><> The same thing happens in the nucleus. An excited nucleus drops down to a lower energy level, releasing a photon.

What causes an electron to go from a ground state to excited state?
Typically, an electron goes into an excited state when a photon (a particle of light) with just the right wavelength strikes it. For most molecules, these photons are in the Ultraviolet / Visible light spectrum.
Why do electrons emit light when they fall down to their ground state?
There's a difference in energy between the excited state and the ground state. The energy has to go somewhere. It's generally emitted as electromagnetic radiation ... "light".
What emits its own light?
The Sun. And also: when electrons go from excited state back to ground level, the energy that they had transforms into light which is given off.

When phosphorous is excited what will its electronic configuration be and Will the excited electron go to 4s orbital as per energy level diagram or 3d orbital and why?
In the case of excited phosphorus, the electron will bump up to the 3d level. This is the next closest location (in terms of energy) that the electron can go. Even though ground state phosphorus has no electrons in 3d, the atom can still access that sub-level because the principal quantum numbers for 3p (where its valence electrons are anyway) and 3d are the same.
