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.
The energy gap between the excited and ground states for the sodium ion is about 2.1 electron volts (eV). This energy difference corresponds to the energy required to excite an electron from the ground state to the excited state in a sodium ion.
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
Yes, because an atom in an excited state will normally give off energy and go to a less-excited state or to its ground state. Some atoms have long-lived excited states and are called "metastable".
An electron possesses more energy in the excited state than the ground state.
In the atomic nucleus as protons and/or neutrons fall from excited states towards their ground state.
Excited state is the opposite of ground state in the context of atoms and molecules. Ground state refers to the lowest energy state of an atom or molecule, while excited states have higher energy levels due to the absorption of energy.
Only gamma, it is the process by which a metastable excited nuclear isomer of an isotope relaxes down to the ground state of the same isotope. Some metastable states must undergo multiple gamma decays through less excited metastable states to reach the ground state.
No, atoms in excited states emit radiation at specific wavelengths, corresponding to the energy difference between the excited state and the ground state. This emission occurs randomly when the atom returns to a lower energy state by releasing a photon.
ground
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.
greater than or equal to the energy gap between its ground and excited states.
No, an electron cannot remain in an excited state without additional energy input. Excited states are temporary and the electron will eventually return to its ground state, releasing the energy it absorbed as photons.
