How can electron emit radio photon Really are photons emitted only by electrons jumping from higher to lower energy levels?

The particle-like features of EM radiation at frequencies of radio waves are almost non-existent. It is far more useful to view such radiation as a vibrating EM-field instead of a photon of almost no energy. When doing so, you can see how a EM wave would result from electrons vibrating back and forth at at set frequency. By setting up an electronic oscillator that has a resonance at a radio wave frequency, you will get electrons vibrating at that frequency; and, from that, an EM wave of that frequency.
> are photons emitted only by electrons jumping from higher to lower energy levels?
No, there are many other ways to accomplish this.

What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
How light is given off by the movement of electrons in an atom?
Electron transitions release photons.
How many photons of light are emitted when the electrons in 50 hydrogen atoms drop from n3 to n1?
1000 ====== In that kind of emitance drop, not a two part cascade drop, only one photon is emitted per electron.
Is excited state of electron have valence electrons?
Normally, yes. 'Ground state' refers to electrons that are unexcited (meaning not pushed to a higher energy level) by heat or electricity. So basically, yes, valence electrons are always at ground state. I mean, unless you're sending an electrical current through the substance.
What is the total collection of photons emitted by a given atom?
Spectrum
When excited electrons return to lower energy levels what is released?
Energy is emitted when an electron moves from a higher energy level to a lower energy level.
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
Can you give some evidences that light is a particle?
Photons interact with matter as a particle; for example, photons can be absorbed and emitted by electrons.
An atom absorbs energy as its electron?
An electron in the ground state does absorb energy in form of photons or other electromagnetic radiations.
Do photon have a greater energy than electron?
No. A photon has no rest mass an electron has mass.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
How light is given off by the movement of electrons in an atom?
Electron transitions release photons.
Is an electron radiation?
Electrons are negative energy. When an electron jumps orbitals, it can either absorb or radiate energy in the form of photons.
How many photons of light are emitted when the electrons in 50 hydrogen atoms drop from n3 to n1?
1000 ====== In that kind of emitance drop, not a two part cascade drop, only one photon is emitted per electron.
How is electromagnetic spectrum related to electrons?
No direct relation; electromagnetic waves are transmitted by photons. However, electromagnetic waves are often caused by the acceleration of electric charges, and those charges are usually electrons. Also, electromagnetic waves are emitted and absorbed when an electron (in an atom) changes to another energy level.
How are electrons involved in light?
None, light is composed of photons. Light may be emitted or absorbed when electrons undergo transitions between atomic or molecular orbitals, but the light itself does not contain electrons.
What form of energy emission accompanies the return of an excited electron to its ground state?
What form of energy emission accompanies the return of excited electrons to the ground state?
