Question
Silver atom has completely filled d orbitals $(4d^{10})$ in its ground state. How can you say that it is a transition element?
✓
Answer
The outer electronic configuration of $Ag (Z = 47)$ is $4d^{10}5s^1.$ It shows $+1$ and $+2O.S. ($in $AgO$ and $AgF_2).$ And in $+2O.S. ,$ the electronic configuration is $ d^9$ i.e., $d -$ subshell is incompletely filled.
Hence, it is a transition element.
