Difference Between an Electron and a Positron?

  1. Apr 17, 2016 #1
    [Mentor's Note: The first 4 posts have been split off from another thread.]

    I want to know why a electron has a different charge than a positron.

    lets use an electron and positron that came to be at the same time and place. They should have split something.
    Can someone explain what it is they split?

    I'll be happy if you could tell me the difference between a electron and positron besides the fact that they fly in opposite directions through a magnetic field.

    'Charge' is simply a property which some subatomic particles have.
    The value of this property for a particle which has it can only be positive or negative. (No intermediate or partial value)
    A positron is a particle whose properties are the same as an electron in all respects other than having opposite charge property.

    The 'fact' that they fly in opposite directions is explained if we consider them to have charges (equal and opposite in value).
    The "What is Charge" question is not part of Physics. It's like the "Why" question.
