What is the definition of excited state electron?

Answer 1

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.

Answer 2

(very basically) Atoms become exited when exposed to energy which results in electrons gaining the energy and jumping up to a higher energy level (electron shell). The electron can loose the energy and fall back down to the lower election shell closer to the nucleus (ground state). The release of Photons (light) is emitted from this process.

Answer 3

An excited atom is one that does not have its electrons in the ground state. The ground state is defined as the configuration of electrons that yields the lowest energy.

An excited atom has more potential energy than an atom in its ground state. This makes the system less stable, and is generally not favored; therefore, the lifetime of atoms in an excited state is usually very short (rare exceptions include singlet oxygen and some nuclear isomers). Atoms are always transitioning between different energy states, but the frequency of this can be changed by adjust the conditions that the atom resides.

For example, heating a sample will cause an increase in translational energy of the atoms in it, which causes a higher population of them to reside in a higher energy state. One can also excite atoms to a specific energy by shooting electromagnetic radiation (EMR). The different energy levels in an atom have specific energies that are discrete values (not continuous) so one can populate specific energy levels using this kind of method.

Answer 4

It means that the electron has absorbed energy and moved into a higher energy level. This is temporary, and as the electron moves back to its ground state, it gives off the same amount of energy that it had absorbed in the form of a photon of light.

Answer 5

An electron from an inner energy level may move to an outer energy level

Answer 6

Atoms are in excited states when the electrons of the atom go from ground state to an upper state. During this state the electron can drop to the ground or stop in an intermediate level.

Answer 7

it's when an element loses one or more electrons from its valence shell

Answer 8

An electron in an excited state is any electron not in its ground state within an atom.
