In the traditional naming convention that distinguishes argentous from argentic silver, which listed oxidation state is associated with argentic silver?

Explanation

In the traditional usage intended here, argentous refers to silver(I) and argentic to bivalent silver, silver(II). The corresponding oxidation state is +2. Modern Stock notation, silver(II), states this directly; valency and signed oxidation state should not be treated as identical quantities in every chemical context.
