The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus.

The configuration of the atom is (1s) 2 , and it has an atomic radius of 0.208nm. Helium forms an hcp solid at low temperatures which has a melting point at - 269.7 C and a density of 0.126. Helium is used for filling balloons and dirigibles. It is mixed with oxygen (heliox) for breathing by deep ocean divers to avoid the "bends" from the nitrogen content of the breathed air.

Atomfysik by Paria Sanai-Farid - Prezi

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. You should already have some appreciation of the factors which govern atomic sizes from the color-coded dot-density diagrams of Hydrogen, Helium, and Lithium and of Beryllium, Boron and Carbon. From the leftmost diagram below, one can see that Hydrogen seems to have a larger atomic radius than Helium, but not larger than Lithium (although it's "radius" is quite spread out). The laser energy used to move the muon up to that unstable state can be used to calculate the radius of the helium nucleus, which is 1.67824 femtometers—one femtometer being one quadrillionth of Helium atomic radius is 31pm, how was this data obtained?
