Aerogels - but this is an artificial compound.
Among naturally occurring metals, Lithium (Li).
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
In general terms, osmium is the most dense element, followed by iridium, and then platinum.
A balloon is less dense than an apple because it is filled with air, which has a much lower density than the solid matter that makes up an apple.
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

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.
Helium is the least dense element at normal conditions.
It is a metal.
The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
Which element changes the density of matter
Lithium is a soft white alkali metal that is the lightest metal under standard conditions. It is also the least dense solid element.
No, gold is a dense, malleable metal at room temperature. It is a solid element on the periodic table.
SOLID Under standard conditions Lithium is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable. For this reason, it is typically stored in mineral oil.
Osmium is the most dense solid in the world. The second-densest solid in the world is a politician's head.
The element Gold would meet these requirements.
In general terms, osmium is the most dense element, followed by iridium, and then platinum.
Lutetium is a solid at room temperature. It is a rare earth metal that has a silver-white color and is a relatively dense and stable element.
