Analyze We must go from the condensed descriptive form of the reaction to the balanced nuclear equation.
Plan We arrive at the balanced equation by writing n and a, each with its associated subscripts and superscripts.
Solve The n is the abbreviation for a neutron \left({}_0^1 n \right), and α represents an alpha particle \left({}_2^4 He \right). The neutron is the bombarding particle, and the alpha particle is a product. Therefore, the nuclear equation is
{}_{13}^{27}Al +{}_0^1 n \longrightarrow{}_{11}^{24}Na +{}_2^4 He \text{or} {}_{13}^{27}Al + n \longrightarrow{}_{11}^{24}Na +\alpha
