"Emission of photons by an atom is not because of the jumping of electrons from an outer shell to an inner shell as current belief, but is caused by the oscillation of electrons in their shells or transitory shells"

An atom has two types of shells

a) Electron shells: - Regions where the electrons are configured in an atom, when the atom in non-excited state.

b) Transitory shells: - Possible regions which the electrons can jump from their 'electron shells', when the electrons are in an excited state.

* Each of the electron shells and transitory shells in an atom act as resonant columns and has their own unique natural frequencies.

* Innermost electron shell has the shortest wavelength frequency and the outermost transitory shell has the longest wavelength frequency that an atom can emit.

* Emission of photons by an atom is caused by the oscillation of its electrons and frequency of photons will be the frequency of the oscillating electrons.

* There is a 90* angle between the oscillation of electrons and emission of photons.

* An atom (of any element) has enormous number of transitory shells and a few electron shells (hydrogen and helium have one electron shell, lithium to neon have two electron shells, sodium to argon have three electron shells so on).

* When an electron oscillates in its shell, the high-density space matter in the inner region of the atom expels the electron to an outer low-density space matter region. I.e. an electron will jump from an inner shell to an outer shell (or, from an inner region to an outer region), when the electron is excited and emits a photon.

Light emission by atoms

From the Stefan- Boltzmann law, we can see that any object with the temperature above absolute zero(0 K) emits radiations. From wien's law, we can see that a very cold object with a temperature of only a few kelvins emits primarily microwaves. An object at "room temperature" (about 295K) emits primarily infrared radiation. And an object with a temperature of a few thousand kelvins emits mostly visible light. An object with a temperature of a few million Kelvins emits most of its radiation in the X-ray wave lengths.

Every shells (electron shells and transitory shells) in an atom have their own unique natural frequencies. The natural frequency of the outermost electron shell of an atom will be in micro wave frequency region and a substance in a very cold temperature (a few Kelvins ) emits microwave. I.e. a few Kelvins of temperature is sufficient for the excitation and oscillation of the outermost electron shell of an atom.

When an electron shell is excited, it will oscillate in its natural frequency and so the electron (s) present in that shell. This oscillation of the electron (s) cause, the 'lines' (see What is light) that formed on the north poles of the electrons will also oscillate and the oscillating magnetic lines will be propagated through space with the velocity of 300000km/s.

In the case of a heavy atom, the natural frequency of the innermost electron shell is in the X-ray frequency region and the excitation of that shell causes the emission of X-rays. Since the density of space matter decreases with the increasing of the distance from the nucleus of an atom, an outer shell's natural frequency will be lower than an inner shell's, and an atom emits low frequency photons when an outer electron shell/transitory is excited. Or in other words, the frequency of an emitted radiation is determined by the position of the electron. The outermost electrons of atoms will radiate microwaves to infrared frequencies when they are exited. But, the innermost electrons of atoms like Tungsten will emit hard X-rays when they are exited.

When an electron is excited, it will jump from its electron shell to an outer transitory shell, because of the density differences between the space matter in the inner and outer regions of the atom. I.e. when an electron oscillates in its shell, for every oscillation towards the direction of the nucleus, the high-density space matter in the inner region of the atom expels the electron to a low-density outer region. This is the reason for the jumping of an atomic electron when it is excited.

Quantum nature of radiation

Since the excitation of an atomic electron is purely because of the excitation of its shell, as the electron jumps from its excited shell to an outer transitory shell, the electron will lose its excitation simultaneously. This is the reason for the quantum or photon nature of radiation by an atom.

If the transitory shell to which the electron has jumped is simultaneously excited by means of a further collision between atoms or the collision of an energetic electron from an external source, that transitory shell will be also get excited and oscillates in their natural frequency. This oscillation of the transitory shell causes, the electron that jumped to that transitory shell will be also get excited and oscillates with the frequency of the transitory shell and causes the emission of a low frequency photon (see Line spectrum of hydrogen atom).

Light emission by an atom: Vertical oscillation of electrons (about the nucleus).

Light reflection by an atom: Horizontal oscillation of electrons (about the nucleus).
