Chemical composition of the sun

  1. This website gives a break down of the ten most abundant elements from spectrum analysis of the sun

    Presumably this result is only valid for the surface/near surface of the sun.

    If there were any heavier elements present wouldn't they have a tendency to sink to the core and therefore be undetectable?

  3. link is broken

    sun is not static
    there is alot of upwelling and mixing
    and the center is the most active area
    as that is where the fusion is happening
    so no stuff willnot just sink and stay in the center
  4. sorry about the link - I've just edited it and it's ok now.

    There wouldn't be any fusion going on in the centre if the centre consisted of elements any heavier than hydrogen. Apparently, our sun doesn't have enough energy to fuse anything heavier than hydrogen.
