Question

A proton and a neutron are both shot at $100m{s}^{-1}$ toward a ${}_6^{12}C$ nucleus. Which particle, if either, is more likely to be absorbed by the nucleus?

• A. The proton.
• B. The neutron.
• C. Both particles are about equally likely to be absorbed.
• D. Neither particle will be absorbed.

Answer 1

The correct option is B The neutron.

${}_6^{12}C$ captures a neutron to form relatively stable element ${}_6^{13}C$.

${}_6^{12}C$ ${+}_0^{1}n\to$ ${}_6^{13}C$

This is more stable than the otherwise formed element ${}_7^{12}N$
