The two most common ones are hydrogen and helium gas
Hydrogen and helium
hydrogen and helium. More than just these two elements can be found in stars, though, otherwise we would live in a universe comprised completely of hydrogen and helium.
Hydrogen and helium
Stars are primarily made of Hydrogen gas (or Hydrogen plasma).The primary reaction in stars to produce energy is called Fusion where two Hydrogen molecules combine to produce one Helium molecule.Thus, a second common element in stars would be Helium (also usually found in plasma form).
the two brightest stars in the orien
A star system can have two or more stars. A star system with two stars is called a binary star system.

what are two elements that can be found in the soiold earths crust
Mostly lighter elements, such as hydrogen (one proton) and helium (two protons). The helium found in young stars comes from nuclear fusion reactions where 2 hydrogens fuse to make a helium atom.
The two most common elements in the Universe, and in most stars are - in that order - hydrogen and helium (elements #1 and #2).
Basically all of them. However, most stars contain large amounts of hydrogen (since that's the most common element in the Universe), as well as helium, as well as smaller amounts of other elements.
Many elements are found in nature in molecular form - two or more atoms (of the same type of element) are bonded together. Oxygen, for example, is most commonly found in its molecular form "O2" (two oxygen atoms chemically bonded together).
Hydrogen and helium
Hydrogen and helium are the most abundant elements in stars.
