Hydrogen and helium
The two common elements found in the sun are Hydrogen and Helium.
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
Hydrogen and helium are the two most abundant elements in the universe.
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.

Hydrogen and helium
Helium cannot be turned into hydrogen to produce energy. Helium and hydrogen are two different elements with different atomic structures and properties. However, fusion reactions involving hydrogen isotopes such as deuterium and tritium can produce energy in a process known as nuclear fusion.
Stars are made from a lot of different elements, but when they are done they are mainly hydrogen and helium.
