Is helium the lighest element?
No, Hydrogen is lighter than Helium. However, Helium is the 2nd lightest element with an atomic number of 2.
What is the symbol of the element helium?
The symbol for the element helium is He.
A star is comprised mostly of what two elements?
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.
