A Review of Elemental Mass Origin and Fundamental Forces Unification for Nuclear and Aerospace Industries

,


INTRODUCTION
Materials mass with its related interactions is a complex and intricate concept of 21st century [1] .Previously, atomic structure of materials was delineated using distinct atomic models [2] , which included Dalton model, Thomson model, Lewis model, Rutherford model, Bohr model, and electron cloud model [3][4][5][6][7] .The studies of these models have solitarily elucidated atomic structure and fundamental atomic particles [8] .The Standard Atomic Model has been refined in the last few decades [9,10] , in which atomic structure and materials mass origin were both expounded [11] .The newly discovered fundamental particles interpreted the 2/8 force-energy relationship and unification of fundamental forces [12,13] .
Herein, the Standard Atomic Model was applied to demonstrate materials (elements) mass origin.The elementary particles, such as quarks, leptons, gluons, photons, bosons and higgs bosons, and their fundamental interactions are manifested for elemental mass origin and forces unifi cation.

STANDARD ATOMIC STRUCTURE
Matter subsist in four fundamental observable states which are solid, liquid, gas, and plasma [14] .Atom is a basic miniature of matter, and, as a fundamental unit, expresses the distinctive physical and chemical properties of matter and chemical elements [15] .The size of atoms is mostly around 100 pico-meters.Conventionally, atom is comprised of a heavy nucleus and bounded electrons, and inside the nucleus exist protons and neutrons [16,17] .The atomic structure of atom can be described using Dalton model, Thomson model, Lewis model, Rutherford model, Bohr model, and electron cloud model.The conventional atomic structure and forces interactions are shown in Figure 1 [8,18] .
In recent decades, physicists and material scientists have developed a Standard Model for materials mass origin description.During experimental research, they discovered more elementary particles [19] .

STANDARD MODEL AND NEW PARTICLES DISCOVERIES
The Standard Model describes the modern atomic structure, unifi cation of fundamental forces, and materials mass origin [20] .The Standard Model comprises copious elementary particles that are classified into fundamental fermions and bosons.The fundamental fermions exist in the form of rudimentary particles of quarks and leptons [21,22] .
The formation of leptons is a result of weak interactions [10,25] .There are six types of leptons, and they occur in pairs, called generations.Totally, there are three generations, known as electron and electron neutrino, muon and muon neutrino, and tau and tau neutrino, with more mass and less stability in higher generations.The results of fundamental interactions of leptons are shown in Figure 2 [26][27][28] .
Quarks are also elementary particles with color charge, electric charge, mass, and spin [29] .Due to these properties, quarks can interact with the four fundamental forces.The strong and weak interactions exist between these fundamental particles.The different three generations of quarks are up, down, charm, strange, top, and bottom [30,31] .The first generation particles are stable, while the unstable second (mesons) and third generations (baryons) decay with short half-lives.Naturally, two up and one down quark mediate through gluons for protons formations.The outcomes of Quarks mediations are shown in Figure 3 [32] .
Gluons mediate with nuclear forces of attractions.The charge interactions of quarks and mediations through strong forces of interactions allow gluons to transform particles (quarks) from one state to another [36] .
The W -and Z vector bosons are massive particles that mediate with leptons and quarks.The light and massive bosons with spin +1 and -1, respectively, interacts with fermions to interchange particles and transmit mass [37,38] .
Photons are fundamental elementary particles belonging to the class of bosons with wave-particle duality.They always move at the speed of 299792458m/s in vacuum as they are massless quantum tiny particles, while tends to behave as particles, when encountering an obstacle.The photons are mediated through electromagnetic fundamental interactions with quarks, leptons, and other elementary particles [39][40][41] .3/8 covalent, ionic, hydrogen and van der Walls [44][45][46][47][48] .
The weak interaction is a type of natural interaction that causes radioactive decay [49] .Weak forces also contribute to fission and fusion reactions [49,50] , and interact with all elementary particles.The fermions (quarks and leptons) interact through bosons to mediate and swap relative flavors.In beta minus decay, for instance, after emission of electron and electron antineutrino, the neutron (down quark) transformed to proton (up quark) [51,52] .
The nucleus, traditionally, is made up of protons and neutrons.The protons and neutrons are bounded together through strong nuclear forces.Collectively, the total number of protons and neutrons in a nucleus are termed nucleons.The radius of nucleus is defi ned as (4)   where A is the number of nucleons [53,54] .
The Standard Model presents a quite different inter pretation of nucleus formation.According to this theory, the protons and neutrons are composed of quarks elementary particles.The formation of quarks is a result of strong interactions.These generations of particles are known according to their six diff erent fl avors, namely, up, down, top, bottom, charm, and strange [55] .

ELEMENTAL MASS ORIGIN AND FORCE UNI-FICATION
The elemental mass origin and forces unifi cation are reverse engineering methodology.The mass gaining and unification start with higgs fundamental scalar particles interactions (Figure 4 and Figure 5).Higgs boson particles interact at high energy excitations, where higgs fi elds were produced.Furthermore, higher energies and temperature arbitrary are kept constant for concept demonstration [56][57][58][59][60] .
Spontaneous symmetry breaking and gravity free are two models for particle mediation [61] , which explain the mediations and generations of elemental mass due to higgs fi eld interactions.The higgs bosons particles are created because of SU (2) symmetry breaking [62] .At higher temperature, vacuum, and energy, higgs field (Quantum field) exist strongly in vacuum around higgs particles.The field pervades in space.At a high temperature, the fi eld originates symmetry breaking in interaction.The SU (2) symmetry breaking activates higgs mechanism.The higgs mechanism allows higgs fi eld to interact with other bosons particles [63]   , which generates mass for W + , W -and Z 0 through electroweak symmetry breaking.According to the Standard Model, the bosons can also decay into quarks with different six flavours like up, down, top, bottom, charm, and strange.Moreover, quarks are building blocks of protons and neutrons.The higgs field interaction is proportional to mass.The higgs bosons also interacts with leptons.As the Standard Model predicts, bosons can also decay into electrons, muon, tau and other building block particles [61,64,65] .

FUNDAMENTAL INTERACTIONS AND ELE-MENTAL MASS
Four fundamental forces interact with elemental mass [42] .The existing interactions are gravitational, electromagnetic, weak, and strong.Mathematically, Gravitational force is described as where F g is gravitational force, m 1 and m 2 masses of interacting bodies, r is central distance between bodies and G is gravitational constant.
According to the equation and gravitational law of interaction, gravity is an innate mutual interaction of mass and energy.The gravitational interaction explains all phenomena and eff ects associated with macroscopic objects [43] .
The electromagnetic interaction is a unifi ed description of magnetism and electrostatic interaction.According to Standard Model theory, these forces unifi ed above 100 GeV energy.Electromagnetism can be described in the form of electromagnetic force.The force formulation is given below where E is the electric fi eld, v is the velocity of the particle, and B is the magnetic fi eld.
The electromagnetic force is accomplished with an electromagnetic field which is made up on electric and magnetic fi elds and causes light emission and propagation.
According to conventional atomic structure, an atom is made up of a nucleus and revolving bounded electrons that are bounded through electrostatic force of attraction.Mathematically, the force is described as where F electrostatic is force, K is coulombic constant, q 1 and q 2 are charges, and r central distance between charges.
Previous studies have stated that the electrostatic interactions (bonding) contribute fundamentally in explaining the basic states of elemental mass, through which atoms are held together.Formally, these interactions are metallic, 4/8 forces unification and atom formations are shown in Figure 4 [44,[71][72][73][74][75][76] .According to Figure 4, at a high temperature, vacuum, and energies, the higgs field provides initial environment to higgs bosons, quarks, and leptons to interact through photons, gluons and bosons.During interaction and mediation, the elementary particles exchange mass to transform from one elementary particle to another.Similarly, within the atom, strong and weak nuclear forces primarily contribute to protons, neutrons, and nucleons (proton + neutron) formations.The weak and strong forces also play a vital role in nucleus emergence.The Figure 5 and Table 1 also explain the media-tion of scalar higgs bosons with gauge bosons such as W + , W -and Z 0 .The interaction and mediation through these gauge bosons form leptons with different masses [77][78][79][80][81][82][83] .
Protons and neutrons form nucleons, which make up 99.99% of atomic mass, and the rest 0.1% is from the electrons.Studies have reported that nucleons interact strong and weak forces of attractions [66][67][68] .Similarly, electrons mediate and interact through electrostatic and electro-magnetic forces of interactions.All elementary particles (including higgs) also experience gravitational force, whose strength depends on the individual mass of the interacting object [69,70] .
[2002] [83] Atomic particles Electron, proton, neutron atomic particles Atomic, Nuclear and semiconductor industries Moreover, electrostatic forces of attraction originate from the opposite charge polarization between leptons (electrons) and quarks (protons).The stabilization of this polarization creates nascent atom.The electromagnetic forces are electrostatic and electrodynamic (electromagnetic) in nature.Therefore, electromagnetic forces of attraction are involved in light propagation.The light propagates in the form of radiations, which are tiny quantum packets of particles.Almost all elements of the periodic table consist of atoms, and each individual element is represented by a different number of elementary particles, which are categorized into metals, non-metals, and gases.Based on elementary particles, the metals are classified by nature as alkali, alkaline, transition, lanthanides, actinides, metalloids, and radioactive.Medical isotopes, superconductors development, touch screen technologies, external beam radiotherapy and semiconductors materials are all applications of the Standard Model in advanced engineering [77][78][79][80][81][82][83] .

CONCLUSION
The atomic and modern quantum theories are reviewed the first time for the elemental mass origin and forces unification.At high energies, the elemental mass transform into higgs bosons, leptons, quarks and photons.According to the Standard Model, in reverse engineering, at a condition with low energies, these particles mediate (photons, gluons and gauge bosons mediations) and interact (gravitational, electromagnetic, weak, and strong interactions) for atom formation.Atoms are building blocks of elements of periodic table.In future, the review article can be used for the implementation of elemental mass origin and forces unification in medical, power, semiconductor, nuclear and defense industries.
