First thing you have to do when you go into name a compound would be whether to two elements are both non metals, one metal and one non metal, and if a transition metal is used.

In this case Ag is silver, a transition metal, and P is a nonmetal. Since there is a transition metal we are going to use roman numeral system to indicate the charge.

So Ag has a charge of+1 where as P has a charge of -3. So we could name this compound Silver (I) Phosphide
