(1 point) Explain what happens if Carbon -12 gains a proton? (4 points) If Carbon-12 were to gain a proton, it wouldn’t be Carbon any longer. It would now have 7 protons, which would mean its Nitrogen. It would now be Nitrogen-13. Explain what happens if Carbon -12 gains a neutron? (4 points) If Carbon-12 were to gain a neutron its mass would be affected. It would still have 6 protons, but now it would have 7 neutrons. It would still be an isotope of Carbon. It would now be Carbon-13.
