10) Which of the following elements is most likely to be produced during a nuclear fusion reaction in the Sun?

helium-4

hydrogen-1

uranium-235

uranium-238

Helium-4 is most likely to be produced during a nuclear fusion reaction in the Sun

Answer: Helium-4

Explanation:

Nuclear fusion is the reaction in which the nuclei combines to form a bigger nuclei. The process of nuclear fusion occur naturally inside the sun because the temperature and density inside the sun is optimum for the reaction to take place.

In the process of nuclear fusion, nuclei of four hydrogen atom fuse to form a helium atom and two positrons. This is an exothermic reaction in which energy is released. The energy produced during nuclear fusion is relatively greater than the nuclear fission.

Helium-4

Explanation:

Nuclear fusion is the process by which two light nuclei joins to form a single heavy nucleus and during this process, a large amount of energy is released.

In case of Sun or other stars in the universe this fusion results in the production of the havoc energy which powers the heat and light of the star.

Inside the sun's core hydrogen atoms undergo fusion resulting in the formation of helium thus releasing a lot of energy which is the reason for sun's light and heat. This process requires the extreme conditions of high temperature and pressure to take place as both the nuclei have a positive charge and thus they repel each other. So in extremely high temperature and pressure the nuclei gains very high speed, so much that before they start repelling each other they just hit each other, thus performing a successful fusion.
