WebIn a proton-proton chain, four hydrogen nuclei are combined to form one helium nucleus; 0.7 percent of the original mass is lost mainly by conversion into heat energy, but some energy escapes in the form of neutrinos (ν). First, two hydrogen nuclei (1 H) combine to form a hydrogen-2 nucleus (2 H, deuterium) with the emission of a positive electron (e +, … WebNov 19, 2024 · The calculation by Yang and colleagues shows that, if the up, down, and strange quark masses were all zero, the proton would still have more than 90% of its experimental mass. In other words, nearly all the …
