Explanation:
Nuclear fusion is a process in which two small nuclei combine together to result in the formation of a larger nuclei.
In Sun, the first step of hydrogen fusion includes combining of two hydrogen nuclei to result in the formation of a deuterium, positron and neutrino.
The nuclear fusion reaction inside the sun is as follows.

Thus, we can conclude that products of step 1 of the hydrogen fusion process in the Sun are isotope of hydrogen, a neutrino, and a positron.

As phosphorus is in need of 3 electrons to gain a stable valence electron configuration, its most likely to bond covalently; share valence electrons with another atom to become stable.
They are important for our health,they give us more energy and we can be more strong and they help us at imunity
