1. \(_{92}U^{235}\) experiences one \(α\) - decay and one \(β\) - decay. Find number of neutrons in the final daughter nucleus that is formed.

\begin{array}{l} Number of neutrons = Mass number - Atomic number \\ = i - i \\ = i \end{array}

2. Calculate the amount of energy released when a radioactive substance undergoes fusion and results in a mass defect of \(2\ kg\).

By substituting the given values in the Einstein's formula, we get

\begin{array}{l} E = i i^{i} \\ = i \times {(i \times 10^{i})}^{i} \\ = i \times 10^{i} J \end{array}
