Introduction
Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at very high speed and join to form a new type of atomic nucleus.
Pre-Requisites:
Nuclear fusion
Activity:
Matters in the universe.
Real Life Question:
What is Nuclear fusion?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Nuclear fusion | Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at very high speed and join to form a new type of atomic nucleus. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Nuclear fusion | Extreme astrophysical events that can lead to short periods of fusion with heavier nuclei. This is the process that gives rise to nucleosynthesis, the creation of the heavy elements during events such as supernovae. |
Real life uses :

| Examples | Explainations |
|---|---|
| Nuclear fission | Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). |
What you learn in Theory:
Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at very high speed and join to form a new type of atomic nucleus.
What you learn in Practice:
Matter is not conserved because some of the mass of the fusing nuclei is converted to photons which are released through a cycle that even our sun uses. Fusion is the process that powers active or "main sequence" stars.
