proton volt?

[Miss Perfect]

do we have such a unit for energy? and if there was such a unit, what would be its relation with electron volt?

I guess they must be equel since they have the same charge but someone said it's 1840 times greater than electron volt.

Step one:

 

Write down the definition of 1eV.

[Miss Perfect]

th energy that's gained by an electron in 1v potential. Could you plz give me an straight answer, be sure that I've thought about it by myself but I want to make it sure, ok?

its the energy gained by accelerating an elementary charge through a potential difference of one volt. the definition does not specifically state an electron.

If we are accelerating a charge with mass, wouldn't the magnitude of that mass be important?

The dynamics of how that charge would accelerate would be different — the proton will go in the opposite direction as an electron, and it will have a different speed. But a fundamental charge that is accelerated through a 1V potential difference gains 1 eV of energy, by definition.

 

So the idea in the OP is right — the pV and eV would be the same, so there's no need for both.
