Which of these statements correctly describes how the chain reaction occurs in nuclear fission.
|
|
Uranium releases electrons to create electricity
|
|
|
When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split
|
|
|
When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split
|
|
|
Protons and neutrons change to electrons because the nuclei are so big
|
Explanation:
Detailed explanation-1: -A reaction that initiates its own repetition. In a fission chain reaction, a fissionablenucleus absorbs a neutron and fissions spontaneously, releasing additional neutrons. These, in turn, can be absorbed by other fissionable nuclei, releasing still more neutrons.
Detailed explanation-2: -Answer: B. Neutrons released during a fission reaction cause other nuclei to split.
Detailed explanation-3: -Extra neutrons generated during fission further attacks nuclei of fissionable material. Thus a given nucleus after fission gives neutrons which then attack another fissionable nucleus. This in turn releases new neutrons which attacks another nucleus. Thus, the process continues.
