Why do the inner planets have more of the lighter elements like hydrogen and helium gas like the outer planets do?

The Sun and its planets formed form a huge cloud (disk) of dust which contained both light and heavy elements, but there were more light elements (hydrogen) than heavy.
As the disk coalesced into the sun and planets the areas close to the young sun were too hot (heated by the sun) for the light elements to condense and settle onto the young inner planets which are therefore rocky, while the outer planets being further from the sun did accumulate the lighter and more volatile elements. However in the centers of the giant planets there are rocky (heavy) cores.

What is the nuclear process that converts helium and hydrogen from lighter to heavier elements?
Nuclear fusion reaction
What two elements of gas is gas planets made up as?
Mainly hydrogen and helium. The reason for this is simply that these are the most common elements in the Universe.
Why hydrogen gas is liquefied first than helium gas?
Because hydrogen is lighter that helium
What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?
The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.
Are plantes and stars the samething?
They are completely different stars are made of hydrogen and helium while planets are made of various elements
What elelments are on Jovian planets?
Hydrogen and helium are the primary elements on those planets.
Which is lighter - helium or hydrogen?
Hydrogen is lighter than Helium.
What is farthest from the sun and mostly made up lighter elements such as hydrogen and helium?
STAR
What is the nuclear process that converts helium and hydrogen from lighter to heavier elements?
Nuclear fusion reaction
What element is the lightest of the elements?
Hydrogen is the lightest of all elements. According to the Periodic Table, its atomic weight is 1.00794 u, even lighter than helium.
What planets could the elements carbon hydrogen arsenic oxygen neon helium and iron come from?
Earth
What is different between gas giants and terrestrial?
Terrestrial planets contain much more of the heavy elements (such as iron and silicon) and less of the lighter elements (such as hydrogen and helium). Terrestrial planets are smaller and denser, and are also closer to the sun, and hence warmer as well. Gas giants are distant and cold.
What are the two main elements found in the stars?
Hydrogen and helium
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.
Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
What two elements of gas is gas planets made up as?
Mainly hydrogen and helium. The reason for this is simply that these are the most common elements in the Universe.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
