NO, sure not.
Helium (He) mass = 4 g/mol
Fluorine gas (F2) mass = 2*19 = 38 g/mol (almost 10 times heavier),
although fluorine gas hardly can be held stable: it is so VERY rective, even in air!!

Is carbon dioxide lighter than helium?
No. Carbon dioxide is heavier than helium.
What happen when a balloon is filled with helium?
Helium is lighter than air and a balloon filled with helium may rise up.
Why does a helium balloon float up when it is released?
Because helium is lighter than air. So helium balloon will rise up.
Why does a helium balloon go up?
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
Is Helium lighter than smoke?
Yes
Is helium lighter or heavier?

Is helium lighter than earth?
yes. helium is lighter than earth or even air.
Helium and neon cant form compounds with fluorine why?
The first Ionization energy of fluorine is less than that of the helium and neon.
Why is helium lighter than CO2?

What is helium and What is its use for?
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
