First Step in Dissociation Process in the Gas Phase for Small Molecules with Neutral Atoms: Application with the Even-Odd Rule and a Specific Periodic Table for Organic and Inorganic Atoms
Dissociations in the gas phase of small molecules have been intensively
studied and dissociation energies of various gases are available in reference
works. Configurations of compounds before and after the dissociation are
usually known, but local charges are not defined. Building on the even-odd rule, the
topic of a series of previous articles by the same author, the objective of
this paper is to show how it can be used to give electronic rules for
dissociations in gases. To this end, a specific periodic table is created and
used. The rules are applied to a selection of more than 30 common molecules,
showing that the even-odd rule and its consequences are useful in explaining
the phenomenon of dissociation in gases.
