Chemical composition of solar system

AI Thread Summary
The discussion centers on the differences in elemental abundance among solar system bodies, despite their common origin from a dust and gas cloud. Two main hypotheses are proposed: the influence of cloud rotation on element distribution and the interaction of the original dust cloud with additional materials. The conversation highlights the complexity of planetary formation and the inconsistencies found in various sources when researching this topic. Key points include the differing compositions of Earth and Mars, particularly their iron-to-silicon ratios, and the unresolved mechanisms behind the ejection of heavy elements from the young Sun. The need for further reading on stellar formation is emphasized to gain a deeper understanding of these processes.

If our solar system originated from the same dust / gas cloud, why do we see such differences in abundance of elements from one body to another. I can come up with two possible answers:

1. Rotation of cloud centrifuged heavier elements towards edge (Almost certainly not true, because it would need to overcome gravity, and composition of solar system bodies does not follow that pattern)

2. At some point in solar system formation original dust cloud, which presumably consisted of mainly light elements, interacted with another material, probably much smaller in quantity, and different in origin.

I am only guessing, so any help on this is welcome.

Why guess when you can easily find the answers on the 'net?

Google (or pick your favorite search engine) the following terms:
planet formation
frost line planet formation
planet migration
 
Also:

Solar wind
terrestrial planets versus jovian planets
rocky planets versus gaesous planets
 
Yes, that's nice, but if you start to google things, you get bunch of information, not necessary consistent with each other, although they are all from trustworthy sources.
One of them being that Earth's and Mars's composition is different, especially Fe/Si ratio, and that C1 model does not hold on Mars. Other thing is water splashing formed Earth from outer solar system. I see that I oversimplified things, but it seems that this issue is far from resolved.

It didn't. The heavy metals were in the protostellar dust cloud when the sun formed. They were formed during the nova deaths of older stars.
 
No, not asking when they were synthesized. Some article I stumbled upon, claims that young Sun ejected what was already in there of heavier elements, not describing mechanism, but I can't see how.
So what would be a book to read on stellar formation?
