H Hydrogen which is the lightest element that is highly flammable element and He Helium the second lightest element with no fire risk. This is why helium is used in making balloons than hydrogen which is much lighter than helium.
That depends on the specific star. However, in most cases the most common element is hydrogen, followed by helium.

Hydrogen and helium; those two elements are the fuel for the stars. First they fuse hydrogen to helium, later they fuse helium to heavier elements.
No, water is a compound of two elements: hydrogen and oxygen. It has the formula H2O, meaning that each molecule of water contains two atoms of hydrogen and one atom of oxygen.
Two.(Two carbons, one oxygen so just two elements.)
If two elements are joined together it is a compound
A chemical compound is comprised of two or more chemical elements. For example, water, H2O, is comprised of hydrogen and oxygen. Some compounds are tremendously more complicated than water, but all compounds are composed of elements.
Phosphorus is an element on the periodic table. Compounds are comprised of two or more elements.
The two most abundant elements in a main sequenced star are Hydrogen(H) and Helium(He).
An element is a single substance where as a compound is a combination of elements eg germanium is an element where as germanium arsenide is a compound....!
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.
The exact mix is different depending on the star's age and size, but hydrogen and helium are always the two most prevalent elements.

The colors and lines in the spectrum of a star indicate the elements that make up the star.
Definitely a compound, because it contains two elements viz. copper and chlorine. NB When any two ( or more ) elements combine it becomes a compound.
