"That is incorrect, although those elements are abandunt in Earth, in the entire universe they are only in negligible quantities. Hydrogen is the most abundant element in the Universe. The Sun and all the other stars are  almost entirely composed of Hydrogen and its isotopes."

Notice I said "Planets" and not stars as you mention the SUN. You ar eright Hydrogen is the most abudant gas in the universe but all the planets within our solar system contains all of these elements. Some more in percentage in others but regardless my point is clear that all these gases are within most of the planets.

>>>>>The gases condensed because of gravitational force of each other. Because of  intense gravitational force, nuclear fusion started which released heat and prevented the "congregation" of molecules from collapsing further. If I recollect correctly, combusion is defined only for burning due to oxidation. <<<<<

Zaman if I may help you out a little here.....

What I was explaining briefly was the Nebular theory which states: Is the slow collapse of a Nebular cloud. While a star is forming in the center of the cloud out the outer regions of the cloud swirl in a disk like structure (perhaps due to its gravitational effect on those outer regions). In the Theory of Condensation, this inc;udes some of the Nebular theory but, it also incorporates some of the interstellar dust that I was talking about which may have formed the planets. Those interstellar grains actually helped cool the the nebular cloud by radiating the heat and at the same time, atoms would also attach. Evenbtually the dust grains grew into large clumps which eventually could form into planets (known as accretion)  with their own grativational fields which attract materials.

the formation of the planets was also due to their region within the cloud. As the Sun eventually formed the inner protoplanets temparture was higher than that of the outer protoplanets as a result, the gaseous moleculre were too high for them to coalesce and eventually dissipated. The outer planets were in colder regions where they barely had enough gravity.

Zaman I have to disagree with you on nuclear fusion. The reason being is because the early system (Solar System that is) was heated by friction, not by fusion because it would occur later at some time. The Angular momentum didn't really really collapse on itself which instead created Protoplanetary disk  (which I've already explained). Eventually have 100 million years or so THERMOnuclear reactions began to occur which allowed for the protosun to become the Sun.

First of all pressure increased because  the cloud was collapsing as a result of its own gravitational field, according to Pressure Law, temperature increased proportionately. I doubt if that can be called "friction". Anyway, that is high-school science, its more than 6-7 years, I don't remember in detail.
