The table gives information about one nuclear reaction that happens in the core of a star.
| Observation | Result |
|---|---|
| Nuclei before the reaction | Two separate nuclei, each containing 1 proton |
| Nuclei after the reaction | One nucleus containing 2 protons |
| Energy transferred to the surroundings | 2.8 × 10⁻¹² J |
Explain how the information in the table shows that nuclear fusion has occurred and that a new element has been produced.
