Question

Isodiaphers are defined as atoms that share the same isotopic number, mathematically expressed as $(N - Z)$ or $(A - 2Z)$. What is the isotopic number for the radioactive nuclide ${}_{92}^{235}U$?

Answer: 51

💡 Solution & Explanation

The mass number $A = 235$ and atomic number $Z = 92$. The isotopic number is given by $A - 2Z$. Calculating this gives $235 - 2(92) = 235 - 184 = 51$.
