I think its hydrogen

hydrogen
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 with 0.09 density
Osmium is the solid element that has the highest density. Opposite of osmium is hydrogen which has the lowest density.
Hydrogen has the lowest density of all elements. Density of it is 0.084 gm-3. It is a diatomic gas.
Tungsten
This element is calcium (Ca) with a density of 1,54 g/cm3.
Hydrogen
Look for the one with the lowest density.
The first three element of the Periodic Table of Elements have the lowest density. They are Hydrogen, Helium and Lithium.
Hydrogen, a gas, has the lowest density at room temperature and pressure (0,00008988 g/cm3).
Hydrogen is the element with the lowest density. With the atomic mass of the H atom being 1, the molecular mass of hydrogen gas, H2 is 2. This molar mass is lower than any other element in the periodic table.
