Question
Why are there many completely ionized helium atoms at
a thousand years after the bang? Select all correct
statements that are both relevant and true. (i.e., is one of
the reasons or causes of why we have many completely
ionized helium atoms at a thousand years after the bang)
1) At a thousand years after the bang the helium nuclei
and electrons have combined to form neutral helium
atoms which stay bound
2) At a thousand years after the bang, the temperature is
too high for any stable helium nuclei formed to stay
bound
3) At a thousand years after the bang, the temperature is
low enough for any stable helium nuclei in existence to
stay bound All nuclei will quickly decay away into free
protons and neutrons Since some helium nuclei are
stable, those isotopes will be in abundance
4) There are not enough free electrons to combine with
helium nuclei to form neutral helium atoms
5) None of the above are correct
