Question
The first artificially radioactive nuclide was discovered by Irene and Frederick Joliot-Curie. They bombarded Aluminum-27 (${}_{13}^{27}Al$) with $\alpha$ -particles to produce a neutron and a new radioactive isotope. Identify this resulting isotope.
Answer: A
💡 Solution & Explanation
The reaction is ${}_{13}^{27}Al + {}_{2}^{4}He \rightarrow {}_{Z}^{A}X + {}_{0}^{1}n$. Balancing mass: $27+4 = A+1 \Rightarrow A=30$. Balancing charge: $13+2 = Z+0 \Rightarrow Z=15$. The element is Phosphorus, giving ${}_{15}^{30}P$.
