Web3 dec. 2024 · Helium/Chemical series Helium, neon, and xenon are in the same group, which are the noble gases (group 18/VIIIA). All of the atoms of the noble gases have filled valence shells–two valence electrons for helium, and eight valence electrons for the rest. This makes them very non-reactive, which is a hallmark of the noble gases. Web22 okt. 1995 · Liquid Helium is called a "quantum fluid" as it displays atomic properties on a macroscopic scale. The viscosity of liquid helium is 25 micropoises (water has a viscosity of 10,000 micropoises). As helium is cooled below its transition point, it has an unusual property of superfluidity with a viscosity approaching zero micropoises.
