Question

what is the mass and charge of proton and electron?

Answer 1

I don't know whether you have asked about absolute or relative but I will write both.
Electron :
Absolute charge : (-) 1.6*10^-19 C
Relative charge : -1
Absolute mass : 9.1*10^-31 kg
Relative mass : 1/1840

Proton
Absolute charge : (+) 1.6*10^-19 C
Relative charge : +1
Absolute mass : 1.67*10^-27 kg
Relative mass : 1
