Origin of the elements

  1. Aug 14, 2012 #1
    By choosing among the following five options, what is the main source in the universe for the origin of the elements : silicon, lithium, bismuth, nickel and uranium?

    Primordial nucleosynthesis – fusion in core of low-mass stars – fusion in core of high-mass stars – slow neutron capture in high mass-stars - rapid neutron capture in supernovae.

    Thanks

    Homework questions should be posted in the appropriate homework forum. Please show whatever work you have done so far and explain where you get lost.

    Sorry, next time I will choose the right forum.
    The following is what I think is the right answer but I'd like to be confirmed.

    silicon = Fusion in core of low-mass star
    lithium = Primordial nucleosynthesis
    bismuth = Low neutron capture in high mass-stars
    nickel = Fusion in core of low-mass star
    uranium = Rapid neutron capture in supernovae

    Thanks!

    For nickel I think you mean fusion in the core of a HIGH mass star. Also, isn't silicon one of the last elements produced in high mass stars and not low mass stars? I'm not formally educated in astrophysics so I could be wrong.
