What makes and gives a proton a postive charge and an electron a negative charge?

I'm not sure of your question... If your asking why is a proton "positive" and an electron "negative", it is because we named them that because of the way the two types of charges seem to cancel each other out. We could have just as easily called a proton negative and an electron positive and we would get the same results.

If you are asking why do protons and electrons have charge in the first place, I don't think anyone has an answer to this question. As far as we know, it is just the way nature happens to be.
 
their instrinct properties I guess, well the proton is considered to be build of quarks which carries charges in fracions of 3. But as GO1 wrote, it is just they way nature is.
 
thanks for the help! :)

It's still not clear whether you were asking about the origin of charge itself,
or just why proton is +1 and electron is -1. I'll assume the former, since that
question is more interesting... :wink:

All intrinsic properties of elementary particles have their origin in how
they transform under certain symmetry groups. In the case of electromagnetism,
the group is U(1), i.e: multiplication by a phase factor exp(i theta). For this
group, there are 2 inequivalent representations: you can multiply by
exp(i theta), or by its complex conjugate exp(-i theta). Elementary particles
can be classified by how they transform under such symmetry groups, i.e:
the Poincare group of special relativity, and certain internal symmetry
groups - of which electromagnetic U(1) is just one. The number of different
inequivalent representations of these groups determines how many different
charges there are. In the case of U(1), there are two inequivalent
representations as I mentioned above, and this manifests in nature as
two different electric charges.

The question of whether all this is genuinely "explanatory" or merely
"descriptive" is debatable - but I still think it's interesting, and the whole
group theoretic approach to elementary particles has been stunningly
successful over the past 50-60 years.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
