Question

what are the products of a fusion reaction? check all that apply.
lighter atoms
energy
heavier atoms
a neutron
a proton

Explanation:

In a fusion reaction, lighter nuclei combine to form a heavier nucleus. This process releases a large amount of energy. For example, in the fusion of hydrogen isotopes to form helium, energy is released. Neutrons can also be a product in some fusion reactions (like in the deuterium - tritium fusion: \(^2_1H+^3_1H
ightarrow^4_2He + ^1_0n\)). Lighter atoms are reactants, not products. Protons are not a typical product of fusion reactions in the context of the general description of fusion (the main products are heavier atoms, energy, and sometimes neutrons).

Answer:

energy, heavier atoms, a neutron
