In the proton-proton chain, the mass of four protons is slightly greater than the mass of a helium nucleus. The "lost"" mass a. binds the particles of the nucleus together. b. cancels the positive charge of the two protons that turned into neutrons. c. escapes as light, positrons, or neutrinos. d. is reabsorbed instantly, turning helium back into hydrogen.
In the proton-proton chain, four hydrogen nuclei are converted to a helium nucleus. This does not happen spontaneously on Earth because the process requires a. vast amounts of hydrogen. b. very high temperatures and densities. c. hydrostatic equilibrium. d. very strong magnetic fields.
