The solid element that has the lowest density is lithium. Its density is 0.534 grams per cubic centimeters. Lithium is a metal, and it does not occur freely in nature.
Hydrogen is a nonmetal and it has the lowest density of any element.

Gasses have the lowest density.
Deterium Hydroxide has the lowest density.
In a mixture of different liquids, the one with the lowest density will float to the top.
That depends on the liquid and the solid. Liquid mercury has a very high density. Liquid gasoline has a very low density. At the melting point the density of a liquid and a solid are almost the same.
Density= mass/volume
Osmium is the solid element that has the highest density. Opposite of osmium is hydrogen which has the lowest density.

Hydrogen with 0.09 density
Hydrogen has the lowest density of all elements. Density of it is 0.084 gm-3. It is a diatomic gas.
This element is calcium (Ca) with a density of 1,54 g/cm3.
Tungsten
I think its hydrogen
The solid element with the lowest atomic number is lithium, with an atomic number of 3.
Hydrogen
Of all the solid layers of the earth, the Crust has the least mass. It is the thinest layer, has the lowest density (it floats on the mantle), and in the oceans, it is only about four miles thick.However, the layer with the least mass is not solid, but gaseous. You're breathing it!
Look for the one with the lowest density.
