Range

Helium is the chemical element with atomic number 2, symbol He. It is a noble gas, practically inert, the first of the family of noble gases in the periodic table of elements. While balloons are perhaps the best known use of helium, they are a minor part of all helium use.[61] Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness.
