Solution

The correct answer is "the same size". This is because in an atom, the number of protons (which are positively charged) is equal to the number of electrons (which are negatively charged) making the atom electrically neutral. Therefore, the charge of an electron is the same size as the charge of a proton but opposite in sign.
