Which of the following best predicts the outcome of a fusion reaction involving isotopes of hydrogen?
two hydrogen isotopes form bonds with each other, absorbing a large amount of energy.

the nuclei of the hydrogen isotopes join together to form a heavier element, and energy is released.

isotopes of hydrogen absorb electrons, undergo an increase in energy level, and split into fragments.

the nuclei of the hydrogen isotopes split, resulting in smaller fragments and the release of a large amount of energy.

The correct answer would be the second option. The outcome of a fusion reaction which involves isotopes of hydrogen would be the nuclei of the hydrogen isotopes join together to form a heavier element, and energy is released. A fusion reaction is a nuclear reaction which involves at least two nuclei or atoms combining forming products that are heavier than the reactants. Along with the formation of a new atomic nuclei, energy is released. Fusion of two isotopes of hydrogen, specifically deuterium and tritium, results to the formation of a neutron and a helium-3 atom atom. This reaction happens in the core of the Sun.
