At that point the electron will emit a photon to give away the extra energy. If the new orbital of the electron is not an allowed one (Quantum mechanic tells you which orbital is allowed) we then say that the electron goes into a virtual states (a state that does not exist) and immediately re-emit the photon.
Photons are electromagnetic waves that propagate in wave packet. Those wave packet carry a defined quantized amount of energy. When a photon interact with an electron it will give away its energy to the electron. The electron will have more energy and hence a larger velocity.
Now if we go to second quantization, the photon interacts with the electron because it is the carrier of the electromagnetic force. This covers both the bound and the unbound state of the electron, except that in the bound case still the energy has to be to give a large enough probability of interaction.
•Electrons in an atom in an excited state (hybridisation) those electrons need to come to its ground state as it come to lower energy level (orbit) it needs to lose some energy in form of photons •The another possibility of electrons (e-) emit photons when it colloids with its Anti-particle positron (e+) it emits an photon (γ)
The Electron and Photon relationship. There is a unique relationship between electrons and photons. During the Big Bang the higher frequency photon radiation created electrons and a plasma of quarks and gluons. Then after 380,000 years the universe went dark when all the original photon radiation was used up.
Photons have a spin of one and are said to be massless. The electron creates the electromagnetic force of magnetism and electric force that provides electricity to power motors and all electrical devices. Electrons also create photons and all visible light for us to see this world.
Why is the Electron so Important. As you can see the electron does multiple things, most other particles are less versatile. First of all they captured free protons and created atoms of hydrogen. These atoms formed stars and then electrons created the light to see in this world.
An electron is a fundamental particle called a lepton with a negative charge of one and a spin of one-half. Electrons are attached around each atom and molecule so, they are the energy system of matter. Photons have a spin of one and are said to be massless. The electron creates the electromagnetic force of magnetism and electric force ...
Swedish scientists have made a video showing what an electron looks like. It resembles the old model of an atom with a center particle surrounded by an energy field. This energy field is like a shell that can expand or contract. I believe that the energy field is a photon or like a photon.
After all the photon radiation was used up the microwave cosmic background remains as a remnant. Then electrons start to form atoms. The universe cooled down so that electrons were able to attach to quarks and create protons and neutrons. After more cooling stable atoms formed.
One way is by the photoelectric effect when photons shine on a metal to release electrons and create an electric current. The other way is to apply a voltage to a conductor to produce a current. Our home has electricity because of the flow of electrons.
