Hydrogen is lighter than air, so the force of gravity is overcome by the force of the heavier air pushing on the balloon. Same as why bubbles float to the top of water. When balloon is filled with air there is no competing force so gravity takes over and pulls the balloon down.

Why the balloons are called helium?
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
How do balloons float?
Balloons that are filled with hot air, hydrogen, or helium will float, or rise upward, because the less-dense gases inside them are displaced by the heavier air around them. Balloons will only rise until the gas density inside them is equal to the density outside. In the case of helium balloons, this may be above the elastic limit of the balloon, and it will pop or leak.
The gas used to fill party balloons contains only helium atoms What does This make helium?
Helium molecules have a lower molecular weight than air. This is why balloons filled with Helium will float in the air. Apex:element
What element is used more in making balloons?
Helium is a gas used to inflate lighter than air balloons.
How or in what is helium used?
either for balloons, or whip it's.
Why do big balloons with helium gas floats and buoyed up?
Helium is lighter than air, hence balloons filled with helium will float and rise up.
Why are balloons called balloons?
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
What gas are balloons filled with to make them float?
Helium
How do the Macy's thanksgiving parade balloons float?
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
Why the balloons are called helium?

Why a balloon is filled with helium gas instead of air?
So that the balloons float

Why is there a difference in the size of the balloons after one week which is filled with air and helium?
helium gas is warmer than air.
Why do helium-filled balloons raise in air?
Because helium is a less dense gas than a general air mixture
What is the gas that you use in balloons?
The gas commonly used in balloons is helium. It is lighter than air, which causes the balloon to float when it is filled with helium.
Where can you find helium balloons in new zealand?
Helium grade balloons can be purchased at most large stationary stores, if you desire them to be filled with Helium then a gas supply store would be your best bet.
