Question

The equation \( \, {}^4_1H \rightarrow {}^4_2He + 2\beta^0 + Q \) represents

• A. nuclear fission
• B. nuclear fusion
• C. nuclear disintegration
• D. none of these

Hint:

Nuclear fusion involves the combination of lighter nuclei to form a heavier nucleus, releasing energy in the process.

Answer 1

The Correct Option is B

Step 1: Understanding the Equation.
The given equation represents a type of nuclear reaction where two light nuclei combine to form a heavier nucleus, releasing energy. The equation is: \[ ^4_1H \rightarrow ^4_2He + 2 \beta^0 + Q \] This reaction is characteristic of nuclear fusion, where two hydrogen nuclei (protons) combine to form a helium nucleus, releasing energy and emitting a beta particle (\(\beta^0\)).
Step 2: Analyzing the Options.
- (A) Nuclear fission: Fission is the splitting of a heavy nucleus into lighter nuclei, which is not represented by this equation.
- (B) Nuclear fusion: This is the correct answer. The equation represents nuclear fusion, where lighter elements combine to form a heavier one.
- (C) Nuclear disintegration: Disintegration involves the decay of a nucleus, but this reaction involves combination, not decay.
- (D) None of these: This is incorrect as the correct answer is nuclear fusion.

Step 3: Conclusion.
The equation represents a nuclear fusion reaction, making option (B) the correct answer.
