Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
In contrast to localizing electrons within their atomic orbitals in valence bond theory, the molecular orbital approach considers electrons to be delocalized across the entire molecule. The simple MO diagram of H 2 O is shown on the right. [2] [3] Following simple symmetry treatments, the 1s orbitals of hydrogen atom are premixed as a 1 and b 1 ...
Diagram showing the overall chemical equation. In pure water at the negatively charged cathode, a reduction reaction takes place, with electrons (e −) from the cathode being given to hydrogen cations to form hydrogen gas.
The MO diagram correlates with the experimental photoelectron spectrum for nitrogen. [19] The 1σ electrons can be matched to a peak at 410 eV (broad), the 2σ g electrons at 37 eV (broad), the 2σ u electrons at 19 eV (doublet), the 1π u 4 electrons at 17 eV (multiplets), and finally the 3σ g 2 at 15.5 eV (sharp).
A version of water splitting occurs in photosynthesis but the electrons are shunted, not to protons, but to the electron transport chain in photosystem II.The electrons are used to reduce carbon dioxide, which eventually becomes incorporated into sugars.
The qualitative approach of MO analysis uses a molecular orbital diagram to visualize bonding interactions in a molecule. In this type of diagram, the molecular orbitals are represented by horizontal lines; the higher a line the higher the energy of the orbital, and degenerate orbitals are placed on the same level with a space between them.

Electron atomic and molecular orbitals A Bohr diagram of lithium. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1]
