Is helium an element, mixture or a compound? - Quora. Helium could be considered an element because there is no chemical or nuclear bonds between any of the atoms. Their outermost electron shells are full, with the first level only being able to hold two electrons.

No data for any oxides of helium. Helium is the second most prevalent element in the universe, after hydrogen.However, the atmosphere contains only 5 ppm volume of helium. Helium concentrations in seawater are no higher than 4-7 ppt. Concentrations are relatively low, because helium as a noble gas only occurs as separate atoms, and usually does not react with any other particles.

Compound Forms: Inglés: Español: almost sure adj adjective: Describes a Helium (from Greek: ἥλιος, romanized: Helios, lit. 'Sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Explanation: An element is a pure substance as well, because if we fill up a balloon with just helium gas, it will only contain helium atoms. On the periodic table of elements, helium is element number 2, and so that should tell you that it's an element of course Helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F).
