Helium, chemical element, inert gas of group 18 (noble gases) of the periodic table. the second lightest element, helium is a colorless, odorless, and tasteless gas that becomes liquid at 268.9 degrees celsius. While helium normally has a 0 valence, it seems to have a weak tendency to combine with certain other elements. means of preparing helium difluoride have been studied, and species such as hene and the molecular ions he and he have been investigated. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. the chemical symbol for helium is he. Helium (he) helium is a chemical element of the periodic table with chemical symbol he and atomic number 2 with an atomic weight of 4.0026 u and is classed as noble gas and is part of group 18 (noble gases). Helium is the lightest noble gas with two electrons filling the 1s state to close the first shell. it is the second most abundant element in the universe, following hydrogen. the hydrogen helium abundance ratio is an important clue to the cosmological process.
