Why doesn't helium form compounds?

Answer 1

Helium does not form compounds because of the electrons doesn't attract to nutrons

Helium does not form compounds because the outer (only) shell of electrons is full. This is the valence shell, and in order for elements to form compounds, the valence shell must have available slots. Helium does not have any available slots in the valence shell, hence its inability to form compounds.

Answer 2

Helium is a noble gas and already has a stable electron configuration with a full outer shell, so it does not need to gain, lose, or share electrons to achieve stability. Therefore, helium does not form compounds because it is highly unreactive due to its stable configuration.
