Question

The Sun generates most of its light through a series of nuclearreactions called the proton-proton chain. The overall process ofthese nuclear reactions can be summarized as4 1H 2He + 2 + 2 + 2?where is a small neutral particle called a neutrino, and is a photon (a particle of light), which is alsoneutral. The pre-subscripts on the element symbols H (hydrogen) andHe (helium) indicate the number of protons in the nucleus of eachelement. What is the charge of the unknown entity "?" ?

The answer choices are:
+2e +e 0 e 2e

Which one is correct? I already guessed 0, and that isincorrect.

Thanks!
+2e +e 0 e 2e

Which one is correct? I already guessed 0, and that isincorrect.

Thanks!

Explanation / Answer

if the 2 in front of the He indicates the number of protons, does this mean there is only 1 He atom, or did you mean to write 2 2He, like you wrote 4 1H?
