Preferred Label : electron-counting rules;
IUPAC definition : Rules establishing correspondence between the topology of a molecular structure and
the number of electrons which may be placed into its bonding molecular orbitals. In
the origin of various electron-counting rules lies a general assumption that the completeness
of the valence electron shell of a molecular entity belonging to a certain structural
type serves as the major criterion of structural stability.;
