helium
Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
Yes, hydrogen gas is lighter than air and can make balloons float. However, hydrogen is highly flammable and can be dangerous, so it is not commonly used today. Helium is a safer alternative for making balloons float.
Helium is used for inflating balloons and dirigible airships.
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.
Yes, nitrogen is a suitable gas to put in balloons. It is often used as an alternative to helium because it is non-flammable and does not deplete the Earth's helium supply. However, nitrogen does not have the lifting properties of helium, so balloons filled with nitrogen will not float.

Actually, they do float. They are lighter than air, so they are supposed to float.
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
Helium is the gas usually used now. Hydrogen works, but is inflammable and so dangerous. There are also hot air balloons which require a heater to create the hot air and keep it hot.
helium is less dense than air. :) so helium will float better than air

So that the balloons float

It's the 2nd lightest element so is less dense in air making it float. The 1st lightest element is hydrogen which is flammable which you wouldn't like at a 5 year old's birthday party.
because it can float the balloon and its not flamable so it wont explode
