The Total solution for NCERT class 6-12
Silver atom has completely filled d orbitals (4d10) in its ground state. How can you saythat it is a transition element?
Ag has a completely filled 4d orbital (4d10 5s1) in its ground state. Now, silverdisplays two oxidation states (+1 and +2). In the +1 oxidation state, anelectron is removed from the s-orboital.However, in the +2 oxidation state, an electron is removed from the d-orbital. Thus, the d-orbital now becomes incomplete (4d9).Hence, it is a transition element.
