SPS4 Nuclear Energy Flashcard

Front

The nucleus of a large atom splits and two smaller atoms are formed. Energy is released in the process. What is the name of this process?

Back

fission

One way in which fission differs from fusion is:

Back

Fission involves splitting of atomic nuclei, while fusion involves combining them.
