Question
The charge on a proton is $+1.6 \times 10^{-19} \mathrm{C}$ and that on an electron is $-1.6 \times 10^{-19} \mathrm{C}$. Does it mean that the electron has a charge $3.2 \times 10^{-19} \mathrm{C}$ less than the charge of a proton?

Answer

An electron and a proton have equal and opposite charges of magnitude $1.6 \times 10^{-19} \mathrm{C}$. But it doesn't mean that the electron has $3.2 \times 10^{-19} \mathrm{C}$ less charge than the proton.
