Hello guys, can you help me with a question about the solar nebula, what do you know about it?
I know that the most common gases in the solar nebula are hydrogen and helium, but I need more information.

Hello! By far the most common gases in the solar nebula are hydrogen and helium. They make up about 98 percent. Only 2% of the mass of the solar nebula is made up of other elements combined, more details https://mywebstats.org/what-percentage-of-the-solar-nebulas-mass-consists-of-hydrogen-and-helium-gas/Planetary nebula emits a spectrum of radiation. The spectrum of the planetary nebula is almost identical to that of the H II region; it includes both dim and bright lines from various ion recombinations in addition to bright lines from hydrogen and helium recombinations and forbidden lines that are caused by collisions.
