Explore student journal protons and electrons answer key. The nucleus is itself made up of positively-charged protons, and neutral neutrons : The electric force is what keeps the atom together, because the negatively-charged electrons are attracted to the positively-charged nucleus. For any atom, the number of protons = number of electrons, so the total charge = 0. When the number of protons does not ...
