Common applications: Nuclear power plants and atomic bombs

Define Nuclear Fusion

Light nuclei combine to form a heavier nucleus.

Examples in the universe: Occurs in stars, like the sun

Key Differences: Fission

Uses heavy atoms, fusion uses light atoms.

Fission occurs at lower temperatures.

Key Differences: Fusion

Fusion is the process that powers stars, fusion needs extremely high temperatures.
