The Sun generates most of its light through a series ofnuclearreactions called the proton-proton chain. The overallprocess ofthese nuclear reactions can be summarized as4 1H â 2He +2ν + 2γ + 2?where ν is a small neutral particle called aneutrino, andγ is a photon (a particle of light), which isalsoneutral. The pre-subscripts on the element symbols H (hydrogen)andHe (helium) indicate the number of protons in the nucleus ofeachelement. What is the charge of the unknown entity "?" ?
