Mark_M said:When I say it does not exists I mean, that under some conditions on vector and scalar potentials, the Klein Gordon or Dirac equation will not have a wave function which corresponds to the ground state. Therefore can we conclude from there that under the same conditions the exited states will not exist?
The ground state of an atom or molecule is its lowest possible energy level, while the excited state is any energy level above the ground state. This means that in the ground state, the electrons are in their most stable configuration, while in the excited state, they have absorbed energy and moved to a higher energy level.
Atoms can transition between ground and excited states through the absorption or emission of energy. This energy can come in the form of light, heat, or other forms of radiation. When an atom absorbs energy, its electrons move to a higher energy level, and when it emits energy, its electrons move back to a lower energy level.
The energy of an atom increases when it transitions from the ground state to an excited state, as it absorbs energy. However, this energy is released when the atom transitions back to the ground state, resulting in no overall change in energy.
The ground state of an atom is its most stable configuration, and chemical reactions involve the breaking and forming of chemical bonds, which requires energy. The energy from the excited state of an atom can be used to facilitate these reactions, making ground and excited states crucial in understanding and predicting chemical reactions.
The energy levels of an atom can be determined through various spectroscopic techniques, such as absorption or emission spectroscopy. These techniques involve shining light of different wavelengths on the atom and observing the energy transitions that occur. The resulting spectrum can then be used to determine the energy levels of the atom.
