Why are there many completely ionized helium atoms at a thousand years after the bang? select all correct statements that are both relevant and trueat a thousand years after the bang the helium nuclei and electrons have combined to form neutral helium atoms which stay boundat a thousand years after the bang, the temperature is too high for any helium nuclei formed to stay boundat a thousand years after the bang, the temperature is low enough for any helium nuclei that have been formed to stay boundall nuclei will quickly decay away into free protons and neutronssince some helium nuclei are stable, those isotopes will be in abundancethere are not enough free electrons to combine with helium nuclei to form neutral helium atomsnone of the above are correct
