Scientists can determine the contents of stars using spectrometer (spectrograph or spectroscope.) Basically different compounds give off different wavelengths of of light. By measuring the light you can identify the compound.

When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
What element is the sun mostly made of?
well the sun gets its name by just spiningb a star so its a star . comment please
What are the gases found in the sun?
helium and hydrogen...
Why sun have hydrogen and helium?
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
What two elements are common in the sun?
The two common elements found in the sun are Hydrogen and Helium.
Is the ratio of the amount of hydrogen and helium in the sun increasing or decreasing?
Since hydrogen atoms in the sun are fused into helium atoms, the amount of helium is increasing and the amount of hydrogen is decreasing.
Nuclear fusion on the sun changes hydrogen into?
Helium
Is the sun made up of mostly hydrogen?
Essentially yes; the sun's energy comes from nuclear fusion with hydrogen being converted to helium.
What type of atomic reaction occurs on the sun?
Hydrogen + Helium=BLAST=Hydrogen+Helium=BLAST=Hydrogen+Helium=BLAST=_ _ _ _ _ _ _ _ _ and so on
What does the sun turn into helium?
If you are asking "how helium formed the sun?" then for your information, sun and all the stars are formed mostly from Hydrogen. And if you are asking "How helium is formed in the sun?", the answer is that the Hydrogen in the sun fuses in itself(that's where from the sun get's its energy and luminosity) producing variety of elements like helium, carbon oxygen,iron etc.
What are the Sun's main atmospheric gases?
Hydrogen and helium. Mostly hydrogen.
