Stars kinda famously fuse elements up to iron as part of normal operations. And even if you exclude that, the entire solar system is leftovers from a previous star - all that is inside our current star too. Sure, much of it isn't at the surface, but there's not much of a reason to expect that literally zero of it randomly floats up among the lighter elements.
That said, "heavy ions and atomic nuclei of elements such as carbon, nitrogen, oxygen, neon, magnesium, silicon, sulfur, and iron" makes up only "trace amounts" of the solar-wind plasma [1].
