Respuesta :

Answer:

The number of freely moving neutrons decreases over time.

Explanation:

During a fission reaction, the total number of protons remains the same. In other words, the charge is conserved. It is the neutron number that decreases during a fission reaction.

Therefore, 'The number of freely moving neutrons decreases over time' is the correct answer.
