We use a lot of elements well, alot. Hydrogen is used in welding, producing rocket fuel, filling balloons, and making fuel cells. (Random fact about Hydrogen, 75% of the universe's elemental mass is hydrogen, hydrogen is relatively rare on Earth.) Helium is used as a cooling medium for nuclear reactors, as a gas for supersonic wind tunnels, used for filling balloons and blimps and is used for diving( When mixed with Oxygen). The one I think we use the most is probably Oxygen( we would be dead without it, think about that!)
