Ernest Rutherford carried out the first artificial transmutation in 1919 when he bombarded "N with alpha particles. The result was an oxygen nucleus: "N+He → °F* →"0+p Radiochemists use a shorthand notation to represent transmutations. Omitting the intermediate F* nucleus, the reaction above can be represented as 14N (a, p) 170. Write balanced equations for each of the indicated nuclear bombardments.
