The most common gas in our universe is hydrogen. Its average density is fairly small. The rarest naturally occurring element is francium, so its average density throughout the universe would be the smallest, but in natural concentrations it would be considered fairly dense.
Aerogels are somewhat solid objects that have very low densities. Lithium would be the least dense solid element--it is very light.

∙ 9y agoThe least dense atom matter is hydrogen. The second-most dense matter is helium. That is why, when you you put either gas in a balloon, the balloon rises, trying to float on top of the heavier air around it.
This is just like putting a piece of light wood far under water. It, too, is less dense than the material around it (water), so rises until it is on top of the water, floating.
