Question
Helium and neon do not form compounds with fluorine. Why?

Helium and Neon do not contain d-orbitals in their respective valence shells and hence their electrons cannot be promoted to higher energy levels like other elements in group 18. Therefore, helium and neon do not form compounds with fluorine.
