Silver atom has completely-filled d-orbital(4d^105 s^1) in its ground state. How can you say- itis a transition element?

Answer»

Solution :In addition to the common oxidation state of `+1`, silver ALSO SHOWS `+2` oxidation state in some of its COMPOUNDS. In the `+2` state, -the outer electronic configuration of Ag is `4d^2` and the cf-orbital is incompletely FILLED. ,So Ag is a TRANSITION metal.
