What is the net loss of hydrogen for each full cycle of the proton-proton chain? Explain.

four hydrogen atom are converted into helium, positron, gamma rays and lots of heat.

Explanation:

Proton - Proton cycle is also known as Proton - Proton reaction. It is a thermonuclear reactions chain which is the main source of energy radiated by the Sun and some other stars in the universe.

In a full cycle of proton proton chain reaction, a helium nucleus is formed by the four hydrogen nuclei and a huge amount of energy nearly 0.7 percent of the original mass is lost.

double the distance = divide strength by 4
