When neutrons are bombarded on nucleus of 
, the number of emitted neutrons will be
Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Identify the reaction involving the bombardment of \( \text{U}^{235}_{92} \) with neutrons.
Step 2: In fission reactions, uranium-235 is known to absorb a neutron and become an unstable compound, which may then break apart into two or more fragments.
Step 3: A typical fission reaction of \( \text{U}^{235}_{92} \) also releases a few neutrons during the process.
Step 4: The average number of emitted neutrons in this reaction is usually around 2 to 3.
Step 5: Since option B states 2 and the question requires an approximation, 2 is the most commonly accepted average value.
Therefore, the correct answer is B.
