What does the change of an atom from an excited state to the ground state always require?
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.
What else can I help you with?
An atom in an excited state contains more of what type of energy than the same atom in the ground state?
more electrons than an atom in the ground state
State in which electrons have jumped to a higher energy level?
state in which electrons have absorbed energy and "jumped" to a higher energy level
What is an exciplex?
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.

How are the colors produced by a chemical when it burns related to the atomic structure of the chemical?
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.
Is a bomb exploding a physical change?
An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
What has a higher energy ground state or excited state?
ground
When radiation is absorbed by a hydrogen electron the hydrogen atom changes its ground state to?
When a hydrogen electron absorbs radiation, it moves to an excited state. The electron jumps to a higher energy level, causing the hydrogen atom to change its ground state to an excited state.
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.
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)
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".
Will the total number of electrons change when a specific element's electrons gain energy to shift from the ground state to the excited state?
No. The atom in this case i not ionised.
Is the electron configuration of sodium an excited state or ground state?
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
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.
Does gravity always change the velocity of objects?
Only until they hit the ground or the floor.
Is an excited state is less stable than a ground state?
Yes.
Does a water heater require a ground wire?
does a water heater require a ground wire?
In which state does the electron possess more energy?
An electron possesses more energy in the excited state than the ground state.
