The charge of a proton and the charge of all electron has *** (4) the same magnitude and the opposite sign*** ;
Answer: option (4) the same magnitude and the opposite sign. Justification: 1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals). 2) Protons are positive particles that are inside the nuclus of the atom.
3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom. 4) The atoms are neutral (neither positive nor negative) because there are the same number of electrons and protons and their charge are of the same magnitude but different sign:** (+) + (-) = 0: positive + negative = neutral.**
The charge of an electron is equal in magnitude and opposite in sign to that of a proton. Therefore, the correct answer is (4) the same magnitude and the opposite sign. This fundamental property is crucial for the structure of atoms and their interactions.
