No. With gases, the density is proportional to the molecular weight.
The molecular weight of hydrogen H2 is 2. The empiral molecular weight of air, which is mainly a mixture of oxygen and nitrogen, is about 29.

No. Think about is Hydrogen only has one proton, yet oxygen, nitrogen... have many more in their atoms. So if it has LESS protons, it's lighter i.e. less dense. Thats why hydrogen balloons RISE as they are lighter. Thats also why when u collect hydrogen in a chemical test, you overturn the test tube |^|, so the rising hydrogen can be trapped.

Gas Denser Than Air

No. Hydrogen is far less dense than air (oxygen, nitrogen and argon, mostly), and that's why it floats. They used to use hydrogen to make zeppelins float... until the Hindenburg exploded.
That was probably the worst marketing for hydrogen ever.

no ofcourse not. air is denser that hydrogen that's why they fill balloons with hydrogen and helium becuase they are lesd dense.

At sea level, and at 70° F (21.1 ° C) Air density is about 0.0745 lb/ft³
Hydrogen is 0.005612274 lb/ft³
So, it is much lighter than air as you can see.

Yes, of course! That's why the Hindenberg exploded, because it was so dense it reached critical mass.

no, density of air ( average ) is 29 while it of H2 is 2.
