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
What must an electron do to move from excited state to ground 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 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).
How does an excited atom get to a ground state?
An excited atom can return to its ground state by releasing energy in the form of photons. This process is known as spontaneous emission. The released photons have lower energy than the original absorbed photons, causing the atom to transition back to a lower energy state, typically the ground state.
Why an element show excited state?
An element shows an excited state when its electrons absorb energy and move to higher energy levels. This can happen when the element is exposed to heat, light, or electricity. In the excited state, the electrons are in an unstable configuration, and they will eventually return to their ground state by emitting energy in the form of light or heat.
Why electron jumps from ground state to exicted state?
An electron jumps from the ground state to an excited state when it absorbs energy, typically in the form of a photon. This causes the electron to move to a higher energy level, creating an excited state. When the electron later falls back to the ground state, it releases the absorbed energy in the form of a photon.
What 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
When an electron gets excited is energy released or absorbed?
When an electron gets excited, energy is absorbed to move the electron to a higher energy level. This absorbed energy gets released when the electron returns to its original energy level, emitting electromagnetic radiation such as light.
Does an excited electron move up or down an energy level?
The excited electron move up.
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 limit is placed on electrons in the Bohr model in the atom?
A shifting electron will always move from a more excited to a less excited state.
What limitation is places on electrons in the bohr's model of the atom?
A shifting electron will always move from a more excited to a less 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.
An atom absorbs energy as its electron?
An atom absorbs energy as its electron moves to a higher energy level, or an excited state. This process is known as excitation, and the absorbed energy corresponds to the difference in energy levels between the initial and final states.
A state in which an atom has more energy than it does at its ground state?
An atom is in an excited state when it has absorbed energy, causing its electrons to move to higher energy levels. These excited electrons are unstable and eventually return to their ground state by emitting energy in the form of light or heat.
What must an electron do to move from excited state to ground 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.
