Argon has 18 electrons. They are arranged as 2,8,8. Since 8 electrons fill the valence shell, its valency is 0.(8 - 8)

The electronic configuration of argon is 2,8,8. The outermost shell has 8 electrons so there is no need to gain or loose electrons to make it octet(i.e.8 shells in the outermost shell). Hence its valency is 0.
