Nucleus: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:

Let the unknown product be $^{A}_{Z}X$. Balancing the atomic numbers: $92 + 0 = 56 + Z + 0 \Rightarrow Z = 36$. Balancing the mass numbers: $235 + 1 = 144 + A + 3 \Rightarrow A = 236 - 147 = 89$. The element with $Z=36$ is Krypton (Kr), so the product is $_{36}Kr^{89}$.
