2. occurs on the sun: ____________
3. more power per gram: ____________
4. a larger nucleus divides to make a smaller nucleus: ____________
5. two hydrogen atoms fuse to make a helium atom: ____________
6. an atomic bomb: ____________
7. a hydrogen bomb: ____________

for questions 8- 12 indicate if the equation represents fission or fusion (circle one). box below then click edit. then you can start completing the equations.

1. $_{91}^{231}pa\

ightarrow_{77}^{192}ir + $ ____________ fission or fusion

1. $_{2}^{4}he+_{1}^{2}h\

ightarrow$ ____________ fission or fusion

1. $_{4}^{9}be+_{6}^{12}c\

ightarrow$ ____________ fission or fusion

1. $_{92}^{238}u+_{0}^{1}n\

ightarrow_{52}^{128}te + $ ____________ fission or fusion

1. $_{105}^{262}db\

ightarrow_{42}^{96}mo+_{14}^{28}si + $ ____________ fission or fusion

Explanation:

1. Nuclear power plants use nuclear fission, where a large nucleus splits.
2. The sun's energy comes from nuclear fusion, where hydrogen atoms combine to form helium.
3. Fusion releases more power per gram as it involves combining light - weight nuclei.
4. When a larger nucleus divides to make a smaller nucleus, it is fission.
5. Two hydrogen atoms fusing to make a helium atom is fusion.
6. Atomic bombs use nuclear fission of heavy - nuclei like uranium or plutonium.
7. Hydrogen bombs use nuclear fusion.

8 - 12: If a large nucleus splits into smaller nuclei, it is fission; if smaller nuclei combine to form a larger nucleus, it is fusion.
