The " AXE method " of electron counting is commonly used when applying the VSEPR theory.
2.
Using the neutral electron counting scheme, Cr has 6 d electrons and NO?has one electron for a total of 7.
3.
L-type ligands are neutral ligands that donate two electrons to the metal center regardless of the electron counting method being used.
4.
Mingos'1984 paper on the polyhedral skeletal electron pair theory develops Wade's electron counting rules for predicting the molecular geometry of cluster compounds.
5.
Since these compounds tend to be more reactive than compounds that obey their rule, electron counting is an important tool for identifying the reactivity of molecules.
6.
Electron counting of this ferrous complex indicates 6 electrons from the cyclopentadienyl anion, 2 electron from each of the carbonyls, and 2 electrons from the iodide.
7.
These examples show the methods of electron counting, they are a " formalism ", and don't have anything to do with " real life " chemical transformations.
8.
To count the number of electrons during the acquisition of a spectrum with a minimum of error, XPS detectors must be operated under ultra-high vacuum ( UHV ) conditions because electron counting detectors in XPS instruments are typically one meter away from the material irradiated with X-rays.
9.
A simpler method has been proposed for constructing Lewis structures, eliminating the need for electron counting : the atoms are drawn showing the valence electrons; bonds are then formed by pairing up valence electrons of the atoms involved in the bond-making process, and anions and cations are formed by adding or removing electrons to / from the appropriate atoms.
