An atom in which an electron has moved up to a higher level is in an excited state. The lowest state of the atom is called the ground state.Ê
When an atom is in an excited state, it means that its electrons have absorbed energy and moved to a higher energy level farther from the nucleus. This higher energy level is unstable, and the electron will eventually return to its original energy level by emitting a photon of light.
Transfer of an electron from a higher energy orbit (2s) to a lower energy orbit (1s) is not possible because it would violate the energy conservation principle. Electrons naturally occupy the lowest available energy levels in an atom, following the Aufbau principle. This means electrons will only move to higher energy levels if they absorb energy, not by transferring between lower and higher energy levels.
The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).

The electron gains energy.
When an electron is moved to a higher energy level,after absorption, the quantum no longer exists as a separate entity -- its energy has been seamlessly integrated ...into the orbital energy of the electron. If the electon absorbs another quantum, that is likewise integrated seamlessly. if the electron drops down a level toward the nucleus, it emits some of its energy as a quantum, outside the electron, that quantum exists as a photon (electromagnetic radiation). inside an electron, there are no separate or independent quanta. in case of an annihilation, ALL the energy of the electron turns into one quantum (and all the energy of the positron into another quantum).If i didn't do a good job of explaining this, please post in the DiscBrd AND send me a private message, and i will try to clarify.

The electron configuration of sulfur in the excited state is [Ne] 3s2 3p4, rather than the ground state configuration of [Ne] 3s2 3p4. In the excited state, an electron has moved from the 3p orbital to a higher energy level.
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
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.

Gravitational potential energy
In physics an electron volt is a very small unit of energy. An electron volt is the amount of energy gained by the charge of an electron once it has moved across an electric potential difference of one volt.
The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.
When a book is moved from a higher shelf to a lower shelf, the only significant thing that changes is the potential energy of the book: when the book is on the higher shelf, it's potential energy will be higher than when it is on a lower shelf.Potential energy is calculated using the formula:PE = mghWhere:m = mass of the objecth = height of the objectg = force of gravity
