Hydrogen with 0.09 density
Mercury is the smallest of the four inner planets and closest to the sun. It is also the smallest of all eight planets.
The 1st group elements i.e. Lithium,Sodium, Potassium, Rubidium, Cesium and Francium are all low density metals and they react violently with water.
5869 degrees Kelvin. Rhenium would be the last element to go, with tungsten right before at 5555 degrees Celsius.
The Periodic Table states all known Elements, and element's atomic number, and if a element is metalic or non-metalic.
All gases are made up of elements, but some are not pure elements. Some are compounds, which are not the same as elements. For example, CO2 is a compound and a gas, but not an element.
Hydrogen has the lowest density of all elements. Density of it is 0.084 gm-3. It is a diatomic gas.

Iridium is the elemento with the highest density
The element which has been measured to have the lowest density is hydrogen. Not only is hydrogen the least dense element, it is also the most plentiful on earth.
Hydrogen is the least dense of all the elements and all other known substances.
Radon is the densest gaseous element.
Hydrogen because it is only one proton and one electron.
Helium melting point: -272,2 0C Rhenium boiling point: 5 596 0C
