Respuesta :
Answer: The correct answer is heavier elements.
Explanation:
There are two types of nuclear reactions:
- Nuclear fission reactions: In this type of reaction, the heavier atoms splits into two or more lighter atoms. The number of atoms formed in this reaction increases from the given atoms.
- Nuclear fusion reactions: In this type of reaction, two or more lighter atoms combine to form a heavier atom. The number of atoms formed in this reaction decreases from the given atoms.
Thus, the correct answer is heavier elements.
