Of course less denser, because a gas is always less denser than liquid.

Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
Yes, there are at least two: Iodine vapor (molar mass 254) and Radon gas (222, but not natural occurring) are heavier (and so more dense) than Mercury vapor (200 g/mol).
No, it is a gas and is much less dense than water.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.

Hydrogen is approximately 10 times less dense than natural gas. Simply, there is less hydrogen in a given volume than there would be natural gas.

they are gas, and gas is less dense
Natural gas on top of the oil. Natural gas is less dense.
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.

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).
helium is a gas less dense than air.
yes

Yes. By definition, most gases are less dense than most solids. i can't think of a counter example. Plus, the gas inside a hot air balloon is superheated to make it even less dense, as heating things makes them less dense
