Helium is the second most abundant gas in the universe however there are no known compounds of helium why?

Question

Answer

Reasons why there are no known compounds of helium:

1. Chemical Inertness:

Helium is a noble gas, which means it has a full outer shell of electrons and is extremely stable. This stability makes it very unreactive and unlikely to form compounds with other elements.

2. Lack of Electronegativity:

Helium has a very low electronegativity, which is a measure of its ability to attract electrons. This makes it difficult for helium to form chemical bonds with other elements.

3. Size of Helium Atom:

Helium is a very small atom, which makes it difficult for it to form stable compounds with larger atoms. The size mismatch between helium and other elements hinders the formation of chemical bonds.

4. Lack of Available Orbitals:

Helium has only two electrons and does not have any available orbitals to share or receive electrons from other elements. This limits its ability to participate in chemical reactions and form compounds.
