<span>Answer: option (4) the same magnitude and the opposite sign. </span> Justification: <span /><span /><span> </span><span>1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals). </span> <span /><span /><span> 2) Protons are positive particles that are inside the nuclus of the atom. </span><span />
<span>3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom. </span> <span /><span /><span> 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.</span>
