In 1919, Ernest Rutherford demonstrated the first artificial transmutation of an element by bombarding stationary nitrogen-14 nuclei with alpha particles. The reaction is represented by the following equation:
24He+714N→817O+X {}^{4}_{2}\text{He} + {}^{14}_{7}\text{N} \rightarrow {}^{17}_{8}\text{O} + \text{X} 24He+714N→817O+XWhat is particle X\text{X}X?
neutron
proton
deuteron
alpha particle
