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
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.
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 electron transition represents a gain of energy?
All transitions in which electrons move from a lower to a higher level require a gain of energy. example: 2nd to 3rd shell
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
When an electron in an atom moves from a lower energy state to a higher state?
The electron absorbs energy and moves to a higher energy level. This process is known as excitation. The electron can then release the absorbed energy by emitting a photon and returning to a lower energy state.
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 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.

What did Planck say about energy and electron?
He said that electrons can become excited and begin to hop energy levels; when this happens an electron is in the excited state.

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 in a hydrogen atom moves from higher energy level to the lowest level?
When an electron in a hydrogen atom moves from a higher energy level to the lowest level, it emits a photon of energy equal to the difference in energy between the two levels. This photon is released as light, and the electron transitions to the ground state. This process is known as an electron transition or de-excitation.
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.
What electron transition represents a gain of energy?
All transitions in which electrons move from a lower to a higher level require a gain of energy. example: 2nd to 3rd shell
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
What happened to the energyof an electron as it goes farther from the nucleus?
if an electron gains enough energy it jumps to a higher energy level. when this happens the atom is in an "excited" state.
What happens if an atom is supplied with excess energy?
An electron may change to an excited state, and an electron may move to a higher orbit.
