Question
Hi Jayendra, I was hoping you could help me with the following question:

Given that the sun is composed mostly of hydrogen and helium but was formed from the same proto-planetary disc as the rest of the solar system. How is it that most of the heavier elements seem to be concentrated in the planets?

Thanks in advance,

Jez

Answer
Hi,
No!
The relative abundance of elements in all parts of the solar system is the same.
Except, on the sun, the heavy elements have gone all to its center, never to be seen again.
We only see the most abundant element hydrogen most of the time.
regards
Jayen
