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.

What else can I help you with?
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.
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.
When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?
The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.
What happens when an electron moves from a low energy state to a high energy state?
When an electron moves from a low energy state to a high energy state, it absorbs energy. This absorption of energy causes the electron to jump to a higher energy level or orbit further away from the nucleus. The electron is now in an excited state and can later release this energy in the form of light when it returns to a lower energy state.
What state does an electron move to its ground state from in a gaseous atom in order for a photon to be emitted?
In a transition to ground state, a photon is radiated away. It carries off the energy to make a transition to ground state possible. As soon as it is created, the photon is off to the races. It travels away at the speed of light (for the medium in which it is moving).
Does a hydrogen atom expand or contract as it moves from its ground state to an excited state?
A hydrogen atom expands as it moves from its ground state to an excited state. This is because the electron in the excited state is farther away from the nucleus, increasing the average distance between the electron and proton in the atom.
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.
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.
Is that electron moves with same and constant speed in orbit?
yeah but it depend on which quantum level it is and also on the state of the atom whether it is in excited or ground state.
The electron configuration for a Sulfur atom in the excited state?
The electron configuration of a sulfur atom in its ground state is 1s2 2s2 2p6 3s2 3p4. In an excited state, one of the electrons can be promoted to a higher energy level. For example, in an excited state, the electron configuration of a sulfur atom could be 1s2 2s2 2p6 3s1 3p5.
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.
What are ground and excited states?
In an atom, the electron or electrons have a certain normal distance from the atomic nucleus, and when they are at the normal distance, that is described as the ground state. If energy is added to an electron it will move further from the nucleus, or depending upon the amount of energy, may leave the atom entirely. If it moves further from the nucleus it is in an excited state. If it leaves the atom it is ionized.
What happens when an electron moves to a higher level?
The electron gains energy.
What happens when ann electron moves to a higher energy level?
It falls back to its ground state, emitting light of a particular wavelength and color.
What happens when a electron moves to higher energy level?
The electron gains energy.
When going up an energy level what happens?
When an electron moves up an energy level, it absorbs energy in the form of a photon. This causes the electron to jump to a higher energy level and become excited. The electron will eventually return to a lower energy level by emitting a photon of light.
What is the difference between the ground state of an atom and excited state of an atom?
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.
