I am pretty much curious to know what actually an electron is? How it is? What is CHARGE? Why there are two types of charges? How electron produces electric fields? How the oscillation of such field creates EM wave i.e. photons (which has mass)?

I just think that electron creates electric field. And I think that the field are some what elastic like a string and when the charge oscillates, the string like field vibrates and the vibration travels in the electric field as wave.

Is this concept 'LEGAL' with respect to physics?

Furthermore, what are the similarities between electron, or proton or photon (with respect to the matter wave)?

Electron is a fundamental particle (a fermion) that carries a negative charge (1.37*10^-19C). Charge is defined as a property that can generate electric field around.

The electric field is when there is an charge present. So the question is actually very strange. If you are talking about the intrinsic properties, then you must know quantum mechanics and string theory, but it's no longer classical anymore.

And E&M wave is just a fluctuation of E&M field, so you can not ask "How the oscillation of such field creates EM wave". And photon is a quantum which is the particle property of E&M wave, again explained by quantum mechanics, photon is a wave packet.

Don't confuse the mass here with normal mass we say, because the E=mc^2 explain that if there is energy there would be an equivalent mass. So mass of photon simply indicate that photon contains energy.

An electron is a fundamental fermion with spin 1/2, charge -e, mass .5 MeV/c^2.

Look up Electron on wikipedia and follow the various links to other things, like charge, mass, electric field, etc. I gurantee you that you will have a much greater understanding if you spend some doing this. And you'll probably have even more questions afterward, but that is ok!

How did you get that number for the charge? Actually e=-1.602*10^-19C

Sorry, misprinted.

Thanks to all. And one question, does electron have any size or dimension? What does the electron wave mean? And I want to know whether there is some similarities between charge and mass?

Thanks to all. And one question,

That's three questions, not one

does electron have any size or dimension?

Not that we have been able to measure with current experimental technology.

What does the electron wave mean?

This is referring to the wavefunction for the electron in quantum mechanics.

And I want to know whether there is some similarities between charge and mass?

They are both single-syllable English words containing the letter "a", they are both properties of fundamental particles in the standard model. I am sure there are more.
