Phenomenological classification of the chemical bonding types by bondonic (mass,
velocity, charge and life-time) properties abstracted from Table 12.1; the used symbols are:

and the specific values for various bonding types that are to be computed for a
given chemical bonding in a molecular structure. Note that defining the bondonic
life-time by Eq. (12.17) is the most adequate, since it involves the basic bondonic
(particle!) information, mass and velocity; instead, when directly evaluating the
bondonic life-time by only the bonding energy one deals with the working formula

that usually produces at least one order lower values than those computed upon
employing the more complex Eq. (12.17). This is nevertheless reasonable, because
in the last case no particle information was considered, so that the Eq. (12.18) gives
the time of the associate
wave
representation of bonding; this departs by the case when
the time is computed by Eq. (12.17) where the information of bonding is contained
within the
particle
(bondonic) mass and velocity, thus predicting longer life-times,
and consequently a more susceptible timescale in allowing the bondonic observation.
Therefore, as far as the chemical bonding is modeled by associate bondonic particle,
the specific time of Eq. (12.17) rather than that of Eq. (12.18) should be considered.
Overall, the present study likes to challenge the chemical bonding classification
upon bondons in terms of the above observable quantities, for a given series of silanes
(see Sect. 12.4); they will be nevertheless judged against the fuzzy classification of
chemical bonding types in terms of the bondonic-to-electronic mass and charge ratios
ς
m
and
ς
e
, and of the bondonic-to-light velocity percent ratio
ς

observable life-time,

respectively—as summarized in Table

These rules are expected to be further refined through considering the new
paradigms of special relativity in computing the bondons' velocities, especially
