Mostly Hydrogen, a little Helium, and very small amounts of all the other natural elements.
No, the solar nebula was primarily composed of hydrogen and helium, with trace amounts of other elements like carbon and iron. The solar system formed from the gravitational collapse of this nebula, leading to the formation of the Sun and planets.

False. The solar nebula primarily consisted of hydrogen and helium, which made up about 98% of its mass. While carbon, iron, and other elements were present, they were in much smaller quantities compared to hydrogen and helium. These trace elements played a role in the formation of planets and other celestial bodies, but they did not dominate the composition of the solar nebula.
Roughly 2% of the mass of the solar nebula consisted of elements other than hydrogen and helium. These elements include heavier elements like carbon, oxygen, and iron that were essential for the formation of planets and other celestial bodies.
light gasses (H, He) ... hydrogen compounds (H2O CH4 NH3)...rocks...metal
mostly iron and carbon but there are three other elements.
mostly Co2 SOME air but not much!! :$:
Steel is neither, but it is a mixture of iron with carbon
Venus is made up of an iron core and rocky mantle. While it's atmosphere mostly consists of carbon dioxide and nitrogen.
Mostly mild steel. Steel is iron with a bit of carbon alloyed into the metal.
The amount of helium compared to other elements differ but a nebula occurs so late in a stars lifetime that heavy elements have been synthesized. A nebula is thus often a complex combination of several elements mostly between helium and iron.
steel is an alloy consisting mostly of iron and carbon. The carbon content present in the alloy is about 0.2 to 1.7 % by weight.
