Answer:
The correct answer is "Nuclear fusion involves the collision of two nuclei"
Explanation:
Nuclear fusion is a reaction in which two light nuclei unite to form a heavier nucleus, with a mass slightly less than the sum of the masses of the initial nuclei and generally releasing particles in the process. The aforementioned mass defect results in a large release of energy.
Not all fusion reactions produce the same energy, it always depends on the nuclei that bind and the products of the reaction.
A typical nuclear fusion reaction involves combining two isotopes of hydrogen, deuterium and tritium, to form a helium atom plus a neutron.
An example of natural fusion is the energy produced inside the Sun. The fusion of hydrogen nuclei occurs to form helium, releasing in the process a large amount of energy in the form of electromagnetic radiation, which reaches the Earth's surface and which we perceive like light and heat.
