Hydrogen is the least dense gas.

The order is: - solid (the densest) - liquid - gas - plasma
Gas giants like Jupiter and Saturn are the least dense planets in our solar system. They are made up mostly of gases like hydrogen and helium, making their overall density much lower compared to rocky planets like Earth and Mars.
The least dense state of matter is plasma. Plasma is a collection of charged particles that have high energy levels and are not bound together in a solid, liquid, or gas state. It is the most common state of matter in the universe, found in stars and other highly energetic environments.

'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.

Saturn is the least dense planet in our solar system.
Gas is actually the least dense state of matter. In a gas, particles are spread out and have high energy causing them to move rapidly and take up a large volume. Solids are the most dense state because their particles are tightly packed together.
Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water).
The molecules are farther apart in a gas.
bubbles rise to the surface of a heated liquid as it changes to gas because they are less dense than the liquid.
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
Gas as the particles move freely of one another.
