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 ant rotons (with electric charge- e each), positrons (with charge te each), and various neutral particles (including neutrons and neutrinos). For a particular collision you detect the emitted products and find 17 protons, 4 antiprotons, 6 positrons, and 29 neutral particles. How many electrons are also emitted? Number 10 electrons There is a hint available!

Explanation / Answer

remember that protons and antiprotons always exist in pair similarly, electrons and positrons also exist in pair,

the initial number of electrons= final number of electrons- positrons

6 + 7 = , E - 6

E= number of electrons= 19 emitted
