Responses
starts when a neutron slams into an atom, causing two atoms to form one, heavier atom
starts when a neutron slams into an atom, causing two atoms to form one, heavier atom
starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms
starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms
starts when two atoms slam together, causing the larger atom to split into two smaller atoms
starts when two atoms slam together, causing the larger atom to split into two smaller atoms
starts when two atoms slam together to form one, heavier atom
starts when the larger atom splits into two smaller atoms after a neutron slams into it
The correct response is:
starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms
The correct answer is:
"starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms"
Let me explain how to arrive at this answer.
Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, along with the release of a large amount of energy. In the process, a neutron is usually needed to initiate the reaction.
Looking at the options, there are a few key points to consider:
- Nuclear fission involves the splitting of an atom's nucleus, so the answer should mention the splitting of a larger atom into smaller ones.
- It is initiated by a neutron colliding with an atom. This is because the energy carried by the neutron can cause the nucleus to become unstable and split apart.
Based on these points, the correct response is: "starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms".
