Helium (pronunciation: HEE-lee-em) is a colorless, odorless element classified as a non-metal, belonging to the group of inert gases in the periodic table and is represented by the chemical symbol He [1, 2, 3]. It is a monoatomic gas that forms weak diatomic molecules only at temperatures close to -273.15 °C or “the absolute zero” [4].
Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table.
Helium is the most abundant gas in the Earth’s heterosphere (the layer of atmosphere around 80km above Earth). The primary source of helium on Earth are minerals of thorium and uranium, which emit alpha particles (helium nuclei).
helium, Chemical element, chemical symbol He, atomic number 2. A noble gas , it is colourless, odourless, tasteless, completely unreactive, and nontoxic. First found by spectroscopy of the Sun’s atmosphere in 1868, it is the second most abundant and second-lightest element in the universe (after hydrogen).
