Helium Gas Structural Formula. Helium Gas features hexagonal closed pack crystal structure. It belongs to group 18, period 1, s block noble gas. It is named after the Greek word helios. It displays red-orange color when exposed in an electric field. Helium is a monoatomic lightest noble gas found in nature.

Helium has a very low viscosity, a high diffusion coefficient, and the smallest atom of any element. These characteristics make helium very hard to contain. If a system has a leak, helium will escape. Helium gas is therefore used to test for leaks in high vacuum systems, fuel systems, and other containments.
