Question

silver atom has completely filled d orbital (4d10)in its ground state .how can you say that it is a transition element ?

Answer 1

Ag has a completely filled 4d orbital in its ground state.now silver displays two oxidation states [+1 and +2] . in the +1 oxidation state , an electron is removed from the s-orbital.but in the second state  , an electron is removed from the d-orbital.thus ,the d-orbital now becomes incomplete .hence it is a transition element.

Answer 2

.
The transition metals are elements between Group 2 & Group 13
we arranged them and named them transition metals, in the periodic table.
It is a fact. Hence, should accept.
