Almost any gas will work, as long as it doesn't react with the balloon material. Air is the cheapest, Hydrogen is the lightest if you want it to float, but since the Hindenberg disaster it is considered a dangerous substance so we usually use Helium. Other gases have different physical characteristics, like some are fairly heavy compared to the air around us. Some change the rubber or mylar or whatever the balloon is made of into something unexpected. Fun with chemistry!
Helium is the most suitable gas for filling balloons and airships because it is lighter than air and non-flammable, making it a safer alternative to hydrogen. While hydrogen is also lighter and provides better lift, it poses significant fire hazards. Helium's inert properties ensure safety during use, which is why it is the preferred choice for both recreational and commercial applications.
Helium is lighter than air, so balloons filled with helium will float. It is also non-flammable and safe to use. Additionally, helium does not react with other chemicals, making it a popular choice for filling balloons.
Hydrogen is suitable for filling meteorological balloons due to its low density, which allows the balloon to rise easily. It is also highly buoyant, providing the necessary lift for the balloon to ascend. Additionally, hydrogen is relatively inexpensive and readily available, making it a practical choice for this application.
Filling a balloon with enough helium for flight takes a lot of helium, hot air balloons only use hot air because it only takes a couple of tanks of propane to heat the air, which is much more cost effective than filling the balloon with helium. Airships use helium because they are used to stay in the air for extended periods of time, so it makes sense to pay for the helium to fill it once, rather than the propane to keep the air hot.
"hydrogen is denser then air so it sinks . . . . helium is less dense than air so it rises!" Im not sure where the above person got their answer, or even what the originator of the question was talking about.Hydrogen is much lighter than "air" (78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and trace amounts of other gases) Hydrogen with an atomic weight of 1.00794 u, hydrogen is the lightest element.Balloons full of it will deflate faster than balloons full of helium due to its teeny molecule size. but i assure you they do fly.Hydrogen is so light it escapes our atmosphere if released.
Helium is used instead of hydrogen for balloons because it is non-flammable, whereas hydrogen is highly flammable. This reduces the safety risk associated with using hydrogen in balloons. Additionally, helium is more abundant in nature and does not react with other substances, making it a safer and more practical choice for filling balloons.
Hydrogen gas is highly flammable and can easily ignite, posing a safety risk in balloons. Helium gas, on the other hand, is non-flammable and is therefore the preferred choice for inflating balloons to ensure safety.

Although hydrogen is lighter than helium, it is highly flammable and poses a safety risk. Helium is non-flammable, making it a safer choice for filling hot-air balloons. Additionally, helium is readily available and does not react with other substances, making it a more stable option for hot-air balloon use.
For small balloons like individuals often have for recreational use, hot air is much easier to control than either hydrogen or helium.For the occasional blimp, or long distance balloon trip, Helium, while somewhat heavier than Hydrogen, has proven to be far safer.The Hindenburg has proven the inherent dangers of using Hydrogen Gas in blimps. While, in theory, pure hydrogen is not explosive without the presence of oxygen, any rupture in the thin material separating hydrogen from the air atmosphere can prove to be deadly.
Weather balloons are traditionally filled with hydrogen due to its low density and cost-effectiveness. However, helium is a safer alternative because it is non-flammable. The choice between hydrogen and helium depends on safety considerations and budget constraints.

In balloons, it is desirable to use the lightest possible gas. Nitrogen is a relatively heavy gas with Atomic mass no. of 14. Instead, a much lighter gas, Helium, is used. It has an Atomic mass no. of 4. Hydrogen was used a long time ago, since it was the lightest gas. But due to its explosive nature, it is no longer used.
