Helium has benefited the entire human race!
Because it is lighter than air, airships (such as Goodyear advertisement blimps) and balloons are inflated with helium for lift. While hydrogen gas is approximately 7% more buoyant, helium has the advantage of being non-flammable (in addition to being fire retardant). In rocketry, helium is used as an ullage medium to displace fuel and oxidizers in storage tanks and to condense hydrogen and oxygen to make rocket fuel. It is also used to purge fuel and oxidizer from ground support equipment prior to launch and to pre-cool liquid hydrogen in space vehicles. For example, the Saturn V booster utilized Helium.
It is utilized in glasses, ceramics and other synthetic materials.

Helium Helium
What element has 2 protons 1 neutron and 2 electrons?
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
Where and when helium was first discovered anywhere?
Helium is an inorganic element! From Wiki: "An unknown yellow spectral line signature in sunlight was first observed from a solar eclipse in 1868 by French astronomer Jules Janssen. Janssen is jointly credited with the discovery of the element with Norman Lockyer, who observed the same eclipse and was the first to propose that the line was due to a new element which he named helium. In 1903, large reserves of helium were found in the natural gas fields in parts of the United States, which is by far the largest supplier of the gas."
