What are the three products of the first step of proton
First, two hydrogen nuclei (1H) combine to form a hydrogen-2 nucleus (2H, deuterium) with the emission of a positive electron (e+, positron) and a neutrino (ν).
What is the first step in the PP chain?
The pp chain reaction. The first step involves the fusion of two hydrogen nuclei 1H (protons) into deuterium 2H, releasing a positron and a neutrino as one proton changes into a neutron. with the neutrinos released in this step carrying energies up to 0.42 MeV.
What does a PP chain produces?
The proton–proton chain, 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.
What happens to the positron created during the PP chain of nuclear reactions?
The process is called the Proton-Proton (PP) Chain, and it operates inside the Sun and stars of similar mass. So what did we do? 1 positron (this positron will bump into a electron and annihilate, creating a gamma ray - energy!).
