## Abstract

_{B̶}), velocity (v

_{B̶}), charge (e

_{B̶}), and life-time (t

_{B̶}). This is quantized either in ground or excited states of the chemical bond in terms of reduced Planck constant ħ, the bond energy E

_{bond}and length X

_{bond}, respectively. The mass-velocity-charge-time quaternion properties of bondons’ particles were used in discussing various paradigmatic types of chemical bond towards assessing their covalent, multiple bonding, metallic and ionic features. The bondonic picture was completed by discussing the relativistic charge and life-time (the actual zitterbewegung) problem, i.e., showing that the bondon equals the benchmark electronic charge through moving with almost light velocity. It carries negligible, although non-zero, mass in special bonding conditions and towards observable femtosecond life-time as the bonding length increases in the nanosystems and bonding energy decreases according with the bonding length-energy relationship ${E}_{\mathit{\text{bond}}}[\mathit{\text{kcal}}/\mathit{\text{mol}}]\times {X}_{\mathit{\text{bond}}}[\stackrel{0}{A}]=182019$, providing this way the predictive framework in which the B̶ particle may be observed. Finally, its role in establishing the virtual states in Raman scattering was also established.

## 1. Introduction

## 2. Method: Identification of Bondons (B̶)

- Considering the de Broglie-Bohm electronic wave-function/spinor Ψ
_{0}formulation of the associated quantum Schrödinger/Dirac equation of motion. - Checking for recovering the charge current conservation law$$\frac{\partial \rho}{\partial t}+\nabla \overrightarrow{j}=0$$
- Recognizing the quantum potential V
_{qua}and its equation, if it eventually appears. - Reloading the electronic wave-function/spinor under the augmented U(1) or SU(2) group form$${\Psi}_{G}(t,x)={\Psi}_{0}(t,x)\mathrm{exp}\left(\frac{i}{\u0127}\frac{e}{c}\aleph (t,x)\right)$$$${\aleph}_{0}=\frac{\u0127c}{e}\sim 137.03599976\left[\frac{\mathit{\text{Joule}}\times \mathit{\text{meter}}}{\mathit{\text{Coulomb}}}\right]$$
^{–19}Joules (electron-volts)! Nevertheless, for establishing the physical significance of such chemical bonding quanta, one can proceed with the chain equivalences$${\aleph}_{\mathit{\text{B\u0336}}}\sim \frac{\mathbf{\text{energy}}\times \mathbf{\text{distance}}}{\mathbf{\text{charge}}}\sim \frac{\left(\begin{array}{l}\mathbf{\text{charge}}\times \mathbf{\text{potentialdifference}}\end{array}\right)\times \mathbf{\text{distance}}}{\mathbf{\text{charge}}}\sim \left(\begin{array}{l}\mathbf{\text{potential}}\\ \mathbf{\text{difference}}\end{array}\right)\times \mathbf{\text{distance}}$$ - Rewriting the quantum wave-function/spinor equation with the group object Ψ
_{G}, while separating the terms containing the real and imaginary ℵ chemical field contributions. - Identifying the chemical field charge current and term within the actual group transformation context.
- Establishing the global/local gauge transformations that resemble the de Broglie-Bohm wave-function/spinor ansatz Ψ
_{0}of steps (i)–(iii). - Imposing invariant conditions for Ψ
_{G}wave function on pattern quantum equation respecting the Ψ_{0}wave-function/spinor action of steps (i)–(iii). - Establishing the chemical field ℵ specific equations.
- Solving the system of chemical field ℵ equations.
- Assessing the stationary chemical field$$\frac{\partial \aleph}{\partial t}\equiv {\partial}_{t}\aleph =0$$
- The manifested bondonic chemical field ℵ
_{bondon}is eventually identified along the bonding distance (or space). - Checking the eventual charge flux condition of Bader within the vanishing chemical bonding field [26]$${\aleph}_{\mathit{\text{B\u0336}}}=0\iff \nabla \rho =0$$
- Employing the Heisenberg time-energy relaxation-saturation relationship through the kinetic energy of electrons in bonding$$v=\sqrt{\frac{2T}{m}}\sim \sqrt{\frac{2}{m}\frac{\u0127}{t}}$$
- Equate the bondonic chemical bond field with the chemical field quanta (6) to get the bondons’ mass$${\aleph}_{\mathit{\text{B\u0336}}}({m}_{\mathit{\text{B\u0336}}})={\aleph}_{0}$$

_{2}bond mass with respect to the two electrons in isolated H atoms comes from the nuclear motion energy converted (relativistic) and added to the two-sided electronic masses, while the heavier resulted mass of the bondon is responsible for the stabilization of the formed molecule respecting the separated atoms. The H

_{2}bondon seems to be also among the less circulated ones (along the bondon of the F

_{2}molecule) in bonding traveled information due to the low velocity and charge record—offering therefore another criterion of covalency, i.e., associated with better localization of the bonding space.

_{m}>>), smallest charge (ς

_{e}<<), and highest (observed) life-time (t

_{B̶}>>) criteria seem to work well. Other bonds with high covalent character, according with the bondonic velocity criterion only, are present in N≡N and the C=O bonding types and less in the O=O and C–O ones. Instead, one may establish the criteria for multiple (double and triple) bonds as having the series of current bondonic properties as: {ς

_{v}>) and charge (ς

_{e}>) in the CC series (and also among all cases of Table 1). This is an indication that the bond is very much delocalized, thus recognizing the solid state or metallic crystallized structure for this kind of bond in which the electronic pairings (the bondons) are distributed over all atomic centers in the unit cell. It is, therefore, a special case of bonding that widely informs us on the existence of conduction bands in a solid; therefore the metallic character generally associated with the bondonic series of properties {ς

Nevertheless, judging upon the higher life-time with respect to the other types of bonding, the classification may be decided in the favor of covalent behavior. At this point, one notes traces of covalent bonding nature also in the case of the rest of halogen-carbon binding (C–Cl, C–Br, and C–I in Table 1) from the bondonic life-time perspective, while displaying also the ionic manifestation through the velocity and charge criteria {ς

The valence explanation relied on the possibility of higher orders of orbitals’ existing when additional shells of atomic orbitals are involved such as <f> orbitals reaching this way the charge-shift bonding concept [73]; the present bondonic treatment of chemical bonds overcomes the charge shift paradoxes by the relativistic nature of the bondon particles of bonding that have as inherent nature the time-space or the energy-space spanning towards electronic pairing stabilization between centers of bonding or atomic adducts in molecules.
