Hydrogen, its the most abundant thing in the universe other than space and time (and mabye dark matter idk about that) because it has the Atomic Mass of one, meaning anything will sink beneath it unless the hydrogen is unable to flat due to being trapped in something like a ballon.
In short, it has less mass than anything so it has less gravitational pull
OH WAIT, YOU JUST ASKED WHAT IT WAS AND NOT WHY SORRY!!! XD

Is it nitrogen gas fills up in balloons?
In balloons, it is desirable to use the lightest possible gas. Nitrogen is a relatively heavy gas with Atomic mass no. of 14. Instead, a much lighter gas, Helium, is used. It has an Atomic mass no. of 4. Hydrogen was used a long time ago, since it was the lightest gas. But due to its explosive nature, it is no longer used.
What is the lightest nonflammable gas?
The lightest non-flammable gas is Helium.Note: After Helium, Nitrogen technically comes next however it can burn at a very high temperature. Because of this, Neon would be the next lightest truly non-flammable gas.
What gas is the lightest of all elements and is highly flammable?
Hydrogen is the lightest of all elements and is extremely flammable. It is also the most plentiful gas in the universe.
What is the second lightest gas?
The second lightest gas is helium. The lightest gas is hydrogen which is also the lightest element. They are very close on the Periodic Table.
Is hydrogen gas faster than nitrogen gas and why?
Because its lighter! obviously!! Hydrogen is the lightest gas of all.. KNOW THAT!
Was helium the lightest gas?
Hydrogen was, and is, the lightest gas
Is hydrogen gas the lightest gas in the world?
Yes it is, and it's also the lightest gas in the universe.
What is the lightest artificial element?
The lightest artificial isotope is hydrogen-3, also called "tritium". The lightest element that has no naturally occurring isotopes is technetium.
