In a hydrogen fusion reaction two lighter hydrogen nuclei merge to form a heavier more stable helium nucleus. the energy that is released in a hydrogen fusion reaction is

is very large and it provides the needed temperature for another set of fusion

Explanation:

Nuclear fusion is the combination of two atomic nuclei into larger ones.

One of such is used in making hydrogen bonds.

In nuclei fusion,

²₁ H + ²₁ H → ⁴₂He + energy

This is an example of nuclear fusion.

The energy helps to further the fusion process and a chain reaction occurs and a massive amount of energy is released.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
