Wikipedia (Silver is the metallic element with the atomic number 47. Its symbol is Ag, from the Latin argentum, derived from the Greek ????? (literally "shiny" or "white"), and ultimately from a Proto-Indo-European language root reconstructed as *h2er?-, "grey" or "shining". A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.)
It is diamagnetic at room temperature. Susceptibility = - -19.5E-6 emu/mol from this table
With its d9 (spin-1) electronic configuration the Ag2+ cation is isoelectronic with Cu2+. Spin S=1/2
The 4d10 electron configuration of Ag+ do not possess unpaired spin and is diamagnetic.
Similarly, the Ag3+ oxidation state with 4d8 electron configuration is diamagnetic
