Question

Proton - Proton chain reaction is an example of nuclear fusion . Why ?

Answer 1

Answer:

The proton–proton chain reaction, also commonly referred to as the p-p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. ... The proton-proton chain is, like a decay chain, a series of reactions. The product of one reaction is the starting material of the next reaction.

Answer 2

Answer:

In most nuclear reactions, a chain reaction designates a reaction that produces a product, such as neutrons given off during fission, that quickly induces another such reaction. The proton-proton chain is, like a decay chain, a series of reactions.
