Vedclass · Answer

(C) transition element is defined as an element which has an incompletely filled $d$-orbital in its ground state or in any of its oxidation states.Option $C$ represents the electronic configuration of Titanium ($Ti$,$Z=22$),which is $1s^2, 2s^2 2p^6, 3s^2 3p^6 3d^2, 4s^2$.Since it has a partially filled $3d$-orbital $(3d^2)$,it is a transition element.Options $A$,$B$,and $D$ represent noble gases or main group elements with either fully filled or empty $d$-orbitals.

Which of the following electronic configurations represents a transition element?
