PROTON:- It consists of 2 up-quarks and 1 down-quarks. Up-quarks and down-quarks have values +2/3 and -1/3 respectively. Now add them, 2(+2/3)+(-1/3)=+1. Therefore it has positive charge.
ELECTRON:- Electrons are dot particle. They are dimensionless. So, they don't have quarks. Since it's being equal puled by positive charge we know its negative(-) and therefore has value -1.

Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.Forces between quarks are mediated by gluons , with a positive electric charge of+1e elementary charge and mass slightly less than that of a neutron.
