![### Nuclear Reaction Explanation
In the illustrated image, we have a nuclear reaction equation that needs to be balanced and understood. The equation provided is:
\[
\begin{array}{c}
^{7}_{3}\text{Li} + ? \rightarrow ^{4}_{2}\text{He} \\
\\
\Rightarrow \quad ^{7}_{3}\text{Li} + ^{1}_{1}\text{P} \rightarrow 2 \cdot ^{4}_{2}\text{He} \\
\end{array}
\]
**Questions asked:**
1. Why \(^{1}_{1}\text{P}\) instead of \(^{3+ [ ? ] = 2} \)?
2. Why \(^{1}_{1}\text{P}\) instead of \(^{-1}_{0}\text{e}\) or \(^{-1}_{1}\text{B}\)???
**Detailed Explanation:**
The reaction explores how Lithium (\( ^{7}_{3}\text{Li} \)) combines with an unknown particle to form Helium (\(^{4}_{2}\text{He}\)).
Through analysis:
1. On the left side of the reaction, Lithium (\( ^{7}_{3}\text{Li} \)) has a mass number of 7 and an atomic number of 3.
2. On the right side, Helium (\(^{4}_{2}\text{He}\)) has a mass number of 4 and an atomic number of 2.
To balance the equation:
- The mass number on the left must equal the mass number on the right.
- Similarly, the atomic number on the left must equal the atomic number on the right.
From the corrected equation:
\[
^{7}_{3}\text{Li} + ^{1}_{1}\text{P} \rightarrow 2 \cdot ^{4}_{2}\text{He}
\]
A proton (\(^{1}_{1}\text{P}\)) with a mass number of 1 and an atomic number of 1 is added to balance the equation.
