Given:
The statement: The Sun's energy is from atomic fission.
Required: To determine whether the given statement is true or false.
Step-by-step explanation:
Atomic fission is the process where a heavier parent nucleus is divided into two lighter daughter nuclei.
Atomic fusion is the process where two lighter nuclei are combined to form a heavier nucleus.
In both these processes, energy is released.
Sun is a star and it has lighter atoms, so it can undergo atomic fusion.
Final Answer: The given statement is false.
