100% of hydrogen is lighter than air
hydrogen
Hydrogen gas is a basic gas that is lighter than air. It is commonly used in weather balloons and airships due to its buoyant properties. However, it is highly flammable and must be handled with caution.
Balloons filled with it float in air
Hot air, hydrogen or helium are lighter than cold air.
Hydrogen gas is 16x lighter than air. The atomic weight of Hydrogen is 1 atomic mass unit, and the atomic weight of oxygen is 16 atomic mass units. 602,000,000,000,000,000,000,000 hydrogen molecules would weigh 1 gram. The same amount of oxygen would weigh 16 grams. Clarification: The air we breath is actually a mixture of oxygen, nitrogen, and carbon dioxide. But in this example, I treated it as pure oxygen to keep things simple.
HYDROGN IS 14 TIMES LIGHTER THAN AIR.
There are many, but one is Helium

this happens because hydrogen is lighter than air
Hydrogen is lighter than air, which is why it rises upwards in the atmosphere. When collected by the downward displacement of air, the denser air prevents the lighter hydrogen from being fully collected as it continues to rise. This method is more effective for gases that are denser than air.
Hydrogen gas is a basic gas that is lighter than air. It is commonly used in weather balloons and airships due to its buoyant properties. However, it is highly flammable and must be handled with caution.
Balloons filled with it float in air
Hydrogen is less dense than air, so it creates a buoyant force that causes the balloon to rise. This is because the density of the hydrogen inside the balloon is lower than the surrounding air, making it lighter and causing it to float upwards.
Hot air, hydrogen or helium are lighter than cold air.
The gas bags of the Hindenberg were filled with Hydrogen gas. Hydrogen is lighter than air, the same way air is lighter than water. The Hydrogen filled "balloon" floated on the air just as one filled with air would float on water. By letting out gas or replacing it from tanks of compressed Hydrogen, they could control the trim and buoyancy of the airship. Unfortunately, Hydrogen is highly flammable when mixed with air, as we all know from what happened to Hindenberg. Although there are ways to avoid disasters such as the one that befell it, people were afraid and that was, effectively, the end of lighter-than-air transportation for commercial purposes.
