Question

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, antiprotons (with electric charge

Explanation / Answer

Initial charge= 6+ 7 (only nucleus colliding, so no electrons involved)=13

24 neitral particles=0

Net charge of final products=15-2+9=22

Thus, final -initial=22-13=9

Thus, number of electrons emitted=9

Explanation:charge on proton and positron is positive, charge on electron and antiprotons is negative.
