    Helium has two electrons in its energy shell, while argon and neon have 8 electrons in their valence shells. As these have maximum number of electrons in their valence shells, they do not have any tendency to combine with other elements. Hence, they have a valency equal to zero.

    Helium,Neon and Argon have zero valency because they have stable electronic configuration.They neither lose electrons nor gain electron.Hence,their valency is zero.
