Give the number of d electrons ( n of $d^{n}$ ) for the central metal ion in (a) ${[{TiCl}_{6}]}^{2 -}$ ; (b) $K [{AuCl}_{4}]$ ; (c) ${[{RhCl}_{6}]}^{3 -}$ .

Short Answer

Expert verified

0 d electrons
8 d electrons
6 d electrons

Step by step solution

Definition of the electronic configuration

The electron configuration of an element describes how electrons are distributed in its atomic orbitals.

Electronic configuration of a given ion

Electron configuration of Ti: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{2} 4 s^{2} \ln {[{TCl}_{6}]}^{2 -}$ the oxidation state of Ti is $+ 4 ({Ti}^{4 +})$ , so it means we have to remove 2 electrons from the 4 s subshell and 2 electrons from the 3d subshell, which leaves ${Ti}^{4 +}$ with $0 3 d$ electrons.
Electron configuration on localid="1663328440485" $Au : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{1} 04 s^{2} 4 p^{6} 4 d^{10} 5 s^{2} 5 p^{6} 4 f^{14} 5 d^{10} 6 s^{1} InK [AuCl 4$ the oxidation state of Au is $+ 3 ({Au}^{3 +})$ , so it means we have to remove 1 electron from the 6s subshell and 2 electrons from the 5d subshell, which leaves ${Au}^{3 +}$ with 8, 5d electrons.
Electron configuration of $Rh : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2} 4 p^{6} 4 d^{8} 5 s^{1} \ln {[{RhCl}_{6}]}^{3 -}$ the oxidation state of Rh is $+ 3 ({Rh}^{3 +})$ , so we have to remove 1 electron from the 5 s subshell and 2 electrons from the 4d subshell, which leaves ${Rh}^{3 +}$ with 6, 4d electrons.
