Vedclass · Answer

(B) 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.$Hg$ (Mercury) has the electronic configuration $[Xe] 4f^{14} 5d^{10} 6s^2$.In its common oxidation state $(Hg^{2+})$,the configuration is $[Xe] 4f^{14} 5d^{10}$.Since the $d$-orbital is completely filled in both the ground state and the common oxidation state,$Hg$ is not considered a transition element.

Which of the following elements is not considered a transition element?
