For now, it is sufficient to say that objects that are charged contain unequal numbers of protons and electrons. 9. The protons are tightly bound within the nucleus Gaining an electron results in a negative charge, so the atom is an anion. Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom. assume all unshared electrons are shown.
