Hydrogen gas has been largely replaced with helium gas in applications like ballooning and airships primarily due to safety concerns. Hydrogen is highly flammable and poses explosion risks, while helium is non-flammable and safer to use. Additionally, helium is less reactive, making it a more stable choice for various applications. Although helium is more expensive, its safety advantages outweigh the cost for many uses.
Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.
The symbol for hydrogen gas is H2
Hydrogen is not a noble gas.
The gas is helium. Helium is inert and has 2 protons, while hydrogen has 1 proton.
