Helium is the most commonly used gas in balloons because it is lighter than air and gives the balloon its ability to float. Some balloons may also use hydrogen, although it is less common due to its flammability.
Helium gas is commonly used in balloons sold by vendors to make them float.
Helium is the noble gas used in party balloons and weather balloons because it is lighter than air. Its low density makes it ideal for filling balloons as it provides buoyancy without adding much weight.
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.
Balloons are usually filled with air. It is a colourless gas. There are other colourless gas options: helium, hydrogen, methane. Coloured gas options (chlorine, bromine) are generally reactive with the rubber or fabric used in balloon manufacture and are undatisfacoty as balloon fillers.
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.

Foil balloons are filled with helium. Helium is lighter than air and because of this, it is one of the gases that can make a balloon float. It's the preferred gas for these type of balloons because it isn't flammable and is inert, meaning undesired chemical reactions are rare.
