Compared to the charge of a proton, the charge of all electron has
(1) a greater magnitude and the same sign
(2) a greater magnitude and the opposite sign
(3) the same magnitude and the same sign
(4) the same magnitude and the opposite sign

The charge of a proton and the charge of all electron has (4) the same magnitude and the opposite sign

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons circulate the nucleus on a particular path so that electrons are not attracted to the nucleus.

The charge of these three atomic particles is based on the Rutherford experiment. Rutherford experimented with firing alpha rays on a thin gold plate. From this experiment it was found that:

(at this time these particles are called protons located in the atomic nucleus)

From here comes the Rutherford atomic model which states that atoms consist of positively charged particles (protons) and negatively charged electrons around the nucleus.

The charge of 1 proton is equal to a charge of 1 electron, but the sign is different.

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

Charge of 1 electron = e = -1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0
