Helium Element Cube Historical Artifacts Both cubes have the same

Both cubes have the same weight of Ruthenium encased in the acrylic

with an experimentally measured (using x-ray crystallography) density of 22

and steel for corrosion prevention

Osmium is the densest naturally occurring element

Helium Element Cube Historical Artifacts Both cubes have the sameHelium's atomic number is 2 and its symbol is He. Helium is the first noble gas and is colorless, tasteless, odorless, and non toxic. Helium has the lowest boiling point of all of the elements. Helium is named after the Greek god of the sun, Helios. This is because the element was first noticed as researchers observed a solar eclipse and noticed the color signature of helium. Despite helium being used to fill party balloons, it is a non renewable
