Assertion: The reaction; \( _{1} \boldsymbol{H}^{2}+_{0} \boldsymbol{n}^{1} \rightarrow \) \( _{2} H e^{4}+_{0} n^{1} \) will not happen Reason: The equation given is not balanced.

1. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
2. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
3. Assertion is true but Reason is false
4. Assertion is false but Reason is true E. Both Assertion and Reason are false

Correct answer: Assertion is false but Reason is true E. Both Assertion and Reason are false

Solution

The given nuclear equation is not balanced: the left side has mass number 3 and atomic number 1, while the right side has mass number 5 and atomic number 2. So the reason is true. However, the assertion is false because the reaction as written cannot be rejected for the stated reason alone; the equation itself is simply incorrect/unbalanced.
