Verified step by step guidance1
Identify the central metal atom in the coordination compound, which is silver (Ag) in this case.
Determine the ligands attached to the central metal. Here, the ligands are water molecules (H2O), and there are two of them, so the prefix 'di-' is used, resulting in 'diaqua'.
Determine the oxidation state of the central metal. Since the compound is neutral overall and the nitrate ion (NO3) has a charge of -1, the silver must have a +1 charge to balance it, indicated as (I).
Combine the ligand name with the metal and its oxidation state to form the name of the complex ion: 'Diaquasilver(I)'.
Add the name of the counter ion, which is 'nitrate', to complete the name of the coordination compound: 'Diaquasilver(I) nitrate'.
