Question

an important aspect of fission reactions is that they produce ____________ which allow for chain reactions. a electrons b neutrons c protons d quarks

Explanation:

In a fission reaction, a neutron collides with a heavy - nucleus (like U - 235), causing it to split and release more neutrons. These released neutrons can then go on to collide with other U - 235 nuclei, sustaining a chain reaction. Electrons, protons, and quarks are not the key particles for chain - reaction initiation and sustenance in fission.

Answer:

B. neutrons
