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 ...
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).
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.
Two circles indicate a pair of electrons. Typically, a pair of electrons will also indicate a negative charge. By using the colored circles, the number of electrons in the valence shell of each respective atom is indicated, providing further descriptive information regarding the reactive capacity of that atom in the molecule.
