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

Silver atom has completely filled d- orbitals (4d") in its ground state. How can you say that it is a transition element?

A transition element is defined as one which has incompletely filled d - orbitals in its ground state or in any one of its oxidation states Why are Zn Cd and Hg not regarded as transition metals?

On what ground can you say that Sc(Z=21) is a transition element but Zn(Z=30) is not?

Assertion : Zn, Cd and Hg are not considered as transition metals. Reason :d-orbitals in Zn, Cd and Hg are completely filled, both in ground state and in their available oxidation states.

Transition elements are d-block elements, with some exceptions. Usually they are paramagnetic. They show variable oxidation states. They and their compounds show catalytic property Zn (atomic number 30) is not a transition element, though it is a d-block element. Why?

Two compounds of iron are given. FeSo_4, Fe_2(SO_4)_3 (The oxidation state of SO_4 -2 ) a. Identify the compound in which iron shows +2 oxidation state. b. Which of these compound posses Fe^3+ ions. c. write the subshell electronic configuration of Fe^3+ ions d. Give reason for the various oxidation states of transition elements.

Transition metals show variable oxidation states due to tendency of ‘d’ as well as ‘s’ electrons to take part In bond formation:- Which element in the first series of transition elements does not exhibit variable oxidation states and why?
