As an electron in an atom moves from the ground state to the excited state the electron?

The electron gains energy as it moves to a higher energy level


What meant by ground state and excited state?

A ground state is an outer orbital electron of an element that is at its lowest possible energy level. The electron in an excited state has a higher energy level than a ground state electron. The average distance from the nucleus is greater in the excited state than in the ground state.


Is a line spectrum produced when an electron moves from one energy level to a higher energy level?

ground to excited


If an electron has absorbed energy and has shifted to a higher energy level the electron is said to be what?

This electron is called excited.


When an electron falls back to its ground state how much energy is released?

It releases the same amount of energy that it absorbed when it was excited to a higher energy state.


What has a higher energy ground state or excited state?

ground


What happens to an electron when it gains energy?

it get excited and goes to higher energy level.


What is meant by excited state of an electron?

When the electrons are at higher energy level,they are said to be excited state.


What does it mean when an electron is in an excited state?

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.


Which electron configuration represents the electrons of an atom in an excited state?

It depends on the atom. For example, the electron configuration of an atom of boron in the ground state is 2-3. In the excited state, it would be 2-2-1. For an atom of chlorine, the ground state configuration is 2-8-7. The excited state would be 2-8-6-1. When an atom enters the excited state, an electron moves up to a higher energy level and releases energy. An electron in the excited state is not stable until it returns to ground state.


What state is an electron in when is has moved from a lower energy level to a higher energy level?

excited


What is difference between a ground state electrons configuration and an excited state configuration?

The ground state of an electron is the lowest energy state it can be in, due to the pauli exclusion principle and fermi statistics. An excited state is a higher energy state, usually empty of electrons in that atom. When an electron is moved from ground state to an excited state (e.g. by absorbing a photon) it tries to fall back to lower energy states (e.g. by emitting a photon) until it is back at its ground state (which may not be the same ground state if another electron took it first). The ultimate excited state is when the electron escapes the atom altogether, this creates a positive ion.


Which electron configuration represents atom in the excited state?

Excited electrons are on higher levels of the electron clouds. It takes more energy to get them to the higher level, and energy is lost when they fall. When that energy is lost, a an x-ray photon is emitted.


When an electron in an atom moves from a lower energy state to a higher state?

An electrons moves from lower energy to higher energy when it is excited.


What statement describes how an atom in the ground state becomes excited?

The atom absorbs energy, and one or more electrons move to a higher electron shell


What is the difference between a hydrogen atom in the ground state and one in the excited state?

In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).


What must happen to the electron in order for an atom to emit light?

The electron must be excited to a higher energy state and then fall back down to its ground state, during which it emits a photon of light.


What does the electron do when an atom emits a photon?

moves from an 'excited' higher energy level, to a lower energy level.


How can an atom emit an photon?

When an electron is excited to a higher energy state, it absorbs energy. It is unstable and falls back down to its ground state, emitting a photon of light of the same amount of energy that was absorbed.


When an electron jumps up to a higher energy level the atom is in it's?

Excited state


When an electron jumps up to a higher energy level that atom is in its what?

The atom is in its Excited State.


What must occur to excite and electron from a lower energy level to a higher energy level?

One electron will absorb one quantum of energy. When this happens, it will move out one energy level from its ground state to the excited state. After a very short time, the one electron will move back to the ground state, and in doing so, will emit one photon of energy (light).


What does it mean when the electrons are excited?

They are in a higher energy orbital than the ground state.


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

An electron basically jumps back to its previous lower energy state or 'ground' state after 10^-9 seconds of excitation. This is because higher energy states are always unstable and electrons prefer to regain their original 'ground' state, which has lesser energy and the electron is more stable in that configuration. In 'de-excitation' , an electron loses energy in the form of radiation and returns back to its previous energy state. The energy of these radiations is equal to the energy that the electron had gained for excitation from the previous level to its current level.


What will happen 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.
