Question

how is a simple chemical reaction different from fusion? (1 point)
the nuclei combine in a fusion reaction but not in a chemical reaction
energy is released in a fusion reaction, but it is absorbed in a chemical reaction
atoms come together in a chemical reaction, but they are split in a fusion reaction
the atoms are bound to each other by electrons in a fusion reaction.

Explanation:

In a simple chemical reaction, only the electrons are involved in bond - making and breaking. In a fusion reaction, the nuclei of atoms combine. Energy can be released or absorbed in chemical reactions, and is released in fusion. Atoms combine or break in chemical reactions and nuclei combine in fusion. Atoms are bound by electrons in chemical reactions, and nuclei combine in fusion.

Answer:

The nuclei combine in a fusion reaction but not in a chemical reaction.
