The number of neutrons accompanying the formation of 54Xe139 and 38Sr94 from the absorption of a slow neutron by 92U235, followed by nuclear fission is __________________?
Correct answer: C. 3
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
The absorbed neutron gives a total mass number of 236, while xenon-139 plus strontium-94 accounts for 233. The remaining mass number is 3, so three neutrons are emitted.
