Web7 apr. 2024 · The protons are undoubtedly charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all matters are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Web19 jun. 2016 · An atom typically has the same number of negative charged electrons as positive charged protons, so its total charge is neutral. But if the atom loses some electrons, it will have more positive charges than negative charges and is called a positive ion. Likewise, if the atom gains an excess of electrons, it is called a negative ion.
