$_{92}U^{235}$ 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

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