Helium gas , because helium is the most inert element of all, and does NOT ignite, and allows balloons to float. If carbon dioxide was used, then the balloons would fall to the floor. Hydrogen is NOT used , because it is flammable and explosive, when mixed with air.
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.
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.
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.
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
Helium is a gas used to inflate lighter than air balloons.
Helium is a colorless gas that is commonly used to fill balloons to make them float. It is lighter than air and non-flammable, making it safe for use in balloons.
Helium gas is commonly used to fly balloons due to its lighter-than-air properties. It is non-flammable and safe for use in balloons to provide the lift needed for them to float in the air.

Helium to get them to float.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Helium is lighter than air, which allows balloons filled with helium to float. Its low density also makes it safe for use in air-filled spaces.
