Yes, much lighter.
The density of hydrogen is 0.08988 grams per litre, at standard temperature and pressure at sea level.
The density of air is 1.22521 grams per litre, at the same temperature and pressure.

Why hydrogen balloon rise in air?
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
Is ammonia more dense or less dense than air?
Yes ammonia is less dense than air
What is true awarm is less dense than cooler air bwarm air is as dense as cooler air cwarm air has no density dwarm air denser than cool air?
Warm air is less dense than cooler air.
Is ammonia denser than air?
No, ammonia is less dense than air.
Is dry ice more or less dense than air?
It is more dense.
What makes balloons less dense air?
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
Why hydrogen balloon rise in air?
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
Why does a hydrogen filled in balloon rise?
beecause hydrogen is less dense and light then air , easy to fly..the hydrogen in the balloon is lighter than the air outside of it.density of hydrogen is lower than air
What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Is hydrogen denser than air?
No. Hydrogen gas (H2) is much less dense than air (that is why it was once used for flying zeppelin aircraft to keep them aloft).
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Is ammonia more dense or less dense than air?
Yes ammonia is less dense than air
What are the six gases than are less dense than air?
Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.
Why the balloon filled with hydrogen goes up whereas the balloon filled with air comes down?
Hydrogen is less dense than air, ergo it floats. Air is of the same density as air, but the rubber skin around it makes it more dense, ergo it sinks.
How do you make a balloon without a balloon?
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.
Why are the test tubes of hydrogen kept with mouth downwards?
Hydrogen gas, H2, is less dense than air, and so it rises. By keeping the mouth downwards, the hydrogen will remain in the test tube.The density of a gas is directly proportional to its molecular weight (see the Related Question about the density of oxygen and air to the left for why this is), and H2 gas is much lighter than air. The average molecular weight of the molecules in air is 28.97 grams per mole, but the molecular weight of hydrogen gas is only 2.01 grams per mole. Hydrogen gas is more than 14 times less dense than air!
