the fission reactions are
(you may select more than one answer)
select one or more:

Explanation:

Step1: Define nuclear fission

Nuclear fission is a reaction where a heavy nucleus splits into smaller lighter nuclei, often with neutron release, initiated by a neutron bombardment.

Step2: Analyze each reaction

1. Beta decay (nucleus emits electron, mass stays same)
2. Alpha decay (nucleus emits $^4_2\text{He}$)
3. Heavy U-235 splits into Rb-90 + Cs-144, neutrons released: fits fission.
4. Fusion (light nuclei combine into heavier one)
5. Beta decay (nucleus emits electron)
6. Fusion (Be + He combine into C)
7. Heavy U-235 splits into Zr-94 + Te-139, neutrons released: fits fission.
8. Alpha decay (nucleus emits $^4_2\text{He}$)

Answer:

1. $^{235}_{92}\text{U} + ^{1}_{0}\text{n}
