Any gas with a density higher than air. Carbon dioxide will do it, krypton is denser still, and will make it drop quicker. There are others too.

Why do baloons float in air?
Balloons are full of a gas called 'helium', which is lighter than air. The helium is trapped inside the balloon, that's what makes it float.
What gas does make a balloon float?
That would be Helium
Light gaz that float?
When a light gas like heliumis placed in a balloon, it will float.
Why does a balloon float in air?
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
How does temperature affect the gas in a balloon?
Heat expands the gas (any gas) and makes the balloon rise.
Is there something else to float a balloon?
gas

Used to make a balloon float?
helium gas

Will ammonia gas float a balloon?
No, the density is too high.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.
What can you say about the gas inside a balloon?
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
What fills a helium balloon?
Helium which is a lighter-than-air gas, allowing the balloon to float upwards.
What physical property make balloon float?
gas yes boy
