Which of these statements is true? The number of electrons outside the nucleus is the same as the number of neutrons in the nucleus. The mass number of an atom is the number of protons plus the number of neutrons. The atomic number of an atom is the number of valence electrons outside the nucleus. In an ion, the number of electrons must be equal to the number of protons.

The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and seven neutrons. You perform a nuclear physics experiment in which you bombard nitrogen-14 nuclei with very high speed carbon-12 nuclei emerging from a particle accelerator. As a result of each such collision, the two nuclei disintegrate completely and a mix of different particles are emitted, including electrons, protons,...
