It is a super light gas .... trust me
Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
Helium is the lightest non-flammable gas. It is colorless, odorless, and tasteless, making it safe for a variety of applications such as lifting balloons and as a coolant in various industries.
This gas is helium.
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
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.
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.

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 a colorless, odorless, and tasteless inert gas that is used in various applications such as in balloons for parties and in cryogenics for cooling superconducting magnets.
