The electron falling one or more energy shells will produce a photon of energy equal to the difference in energy actually two or more in different directions all adding to the energy
An atom of antimony in its ground state has 3 unpaired electrons.
3 electrons. This can be told from the periodic table. These electrons are in the 2p orbital.
Boron has 2 electrons in its 2p orbitals in its ground state. The 2p subshell can hold a maximum of 6 electrons (2 electrons per orbital), but in the ground state, boron only has 2 electrons in the 2p orbitals.
The total number of valence electrons in Boron's ground state is 2
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).
Light.
Energy must be emitted for an electron to return to the ground state. This energy typically occurs in the form of a photon--a particle/wavelet of light. Flourescent bulbs, for example, conduct a current through a gas knocking electrons into higher, more exicted orbits. As the electrons decay into lower orbits, light is emitted, producing the flourescent glow.
The highest energy state is the excited state, where an atom or molecule has absorbed energy and its electrons are at higher energy levels than their ground state. This state is temporary and unstable, as the electrons will eventually return to their ground state and release the absorbed energy.
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.
The exciting of an electron takes in energy. The fall back to the ground state releases that energy as a photon. The photon is created by the return to the ground state.
An atom of antimony in its ground state has 3 unpaired electrons.
Phosphorus has three unpaired electrons in its ground state.
Electrons generally prefer to be in the ground state, which is the lowest energy level available to them. This state is the most stable configuration, as it minimizes the energy of the atom or molecule. While electrons can be excited to higher energy states, they tend to return to the ground state, releasing energy in the process.
There are 10 electrons in the 4d subshell of the ground state of Xenon.
3 electrons. This can be told from the periodic table. These electrons are in the 2p orbital.
Boron has 2 electrons in its 2p orbitals in its ground state. The 2p subshell can hold a maximum of 6 electrons (2 electrons per orbital), but in the ground state, boron only has 2 electrons in the 2p orbitals.
An atom is in its ground state when all the electrons in the atom occupy orbitals that result in the minimum chemical potential energy for the atom as a whole. An excited atom is one that stores (at least for a brief interval) additional chemical potential energy as a result of at least one of the electrons in it occupying an orbital with higher energy than the orbital(s) the electrons in the same atom would occupy in the ground state of the atom.
