more electrons than an atom in the ground state
electrical potential energy
An atom in an excited state
state in which electrons have absorbed energy and "jumped" to a higher energy level
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.
The transition of excited electrons from one allowed energy level to another. As the excited electrons lose their excess energy and return to the ground state, they give out a photon with an energy directly proportional to the energy difference between the electron levels. The photons (light particle/wave) appear different colours depending on the energy of the photon given off.
1. Atoms do not have energy levels unlike particles like electrons etc.2. The lowest energy for atoms will be 0 at absolute zero temp of 0 deg Kelvin.3. For electrons in all atoms lowest energy is that of 2 electrons nearest to the nucleus.
exciplex An electronically excited complex of definite stoichiometry, 'non-bonding' in the ground state. For example, a complex formed by the interaction of an excited molecular entity with a ground state counterpart of a different structure.

ground
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
Excited State -_-
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
To get excited, it must absorb energy. To get back to its ground state, it releases energy.
Atom in the ground state is stable but atom in excited state is not stable the main reason for this is their energies.Atoms in excited state has more energy so they undergo chemical reaction so they are not stable but atoms in ground state has less energy than the excited state so they dont undergo chemical reaction.
That is known as an excited state.
whenever they are in there most stable state , then they are at their lowest energy level. as u provide energy , they get excited and then upgrade to further energy level . and due to loss of energy , they regain earlier positions.
When the atom absorbs energy of the proper frequency/energy.
An excited electron releases a photon as it returns to ground state.
This electron is in an excited unstable state.
