12. describe what happens during nuclear fission. draw a picture. did you write the answer on your…

Brief Explanations:

Nuclear fission is a process in which the nucleus of an atom splits into two or more smaller nuclei, releasing a large amount of energy. This can occur when a heavy - nucleus like uranium - 235 absorbs a neutron. The resulting smaller nuclei are called fission products, and additional neutrons are also released, which can cause a chain reaction if there are enough fissile nuclei present.

Answer:

During nuclear fission, a heavy atomic nucleus absorbs a neutron, becomes unstable, and splits into two or more smaller nuclei, releasing a large amount of energy and additional neutrons. (Note: I can't draw a picture in this text - based response. But you can draw a diagram showing a large nucleus, a neutron approaching it, the nucleus splitting into smaller nuclei, and the release of neutrons and energy.)
