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.

What is HTE difference between an atom in the ground state and an atom in an excited state?

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.


What is the amount of energy released by an electron as it returned to ground state?

The energy released by an electron as it returns to the ground state is equal to the difference in energy between its initial excited state and the ground state. This energy is typically released in the form of a photon with a specific wavelength determined by the energy difference.


Energy gap between the excited and ground states for the sodium ion?

The energy gap between the excited and ground states for the sodium ion is about 2.1 electron volts (eV). This energy difference corresponds to the energy required to excite an electron from the ground state to the excited state in a sodium ion.


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.


What must an electron do to move from ground state to an excited state?

To move an electron from the ground state to an excited state, it requires an input of energy. It should be equal to the energy difference between the two levels. This energy comes from collision with other molecules and atoms.


Why do electrons emit light when they fall down to their ground state?

When electrons fall down to their ground state, they release energy in the form of photons of light. This is because the energy difference between the higher energy state the electron was in and the ground state is emitted as light. The wavelength of the light emitted depends on the specific energy difference between the two states.


Is energy emitted or absorbed when an electron moves from an excited state to a ground state?

Emitted, and the precise amount of energy that is emitted will depend on what kind of atom, and moving from which excited state. That's how spectrographs can determine what element is present.


Do atoms in excited states emit radiation randomly at any wavelength?

No, atoms in excited states emit radiation at specific wavelengths, corresponding to the energy difference between the excited state and the ground state. This emission occurs randomly when the atom returns to a lower energy state by releasing a photon.


What is the difference between excimer and exciplex?

An exciplex is an excited state whose wavefunction overlaps a neighboring, dissimilar molecule. In contrast to an exciplex, an excimer is an emissive excited state whose wavefunction overlaps two adjacent molecules of like composition.


What has a higher energy ground state or excited state?

ground


What happens when an electron moves from the excited state to the ground state?

when an electron moves from excited state to ground state it emits photons of wavelength equal to the difference between the two energy levels. Consider a hydrogen atom. If the electron is at the second energy level in the atom (the energy of this level is -3.4 eV )it can stay there for about only 10^-8 s and then after that it just to the level below .If it jumps from second to ground state (energy of ground state is -13.6 eV) it emits aphoton of energy = 13.6-3.4 =10.2 eV. .............................Gho$t


Why do elements go from ground state to excited state?

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