5 d electrons
4 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.

Explanation

Electron configuration of Ru: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2} 4 p^{6} 4 d^{7} 5 s^{1}$ In $[Ru {({NH}_{3})}_{5} Cl] {SO}_{4}$ ,the oxidation state of Ru is $+ 3 ({Ru}^{3 +})$ , so we have to remove 1 electron from the 5s subshell and another 2 electrons from the 4d subshell, which leaves $({Ru}^{3 +})$ with 5, 4d electrons.

The electron configuration of Os: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2} 4 p^{6} 4 d^{10} 5 s^{2} 5 p^{6} 4 f^{14} 5 d^{6} 6 s^{2}$ In Naz[Os(CN)], the oxidation state of Os is $+ 4 ({Os}^{4 +})$ , so we have to remove 2 electrons from the 6s subshell and another 2 electrons from the 5d subshell, which leaves ${Os}^{4 +}$ with 4, 5d electrons.

The electron configuration of $Co : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{7} 4 s^{2} \ln [Co {({NH}_{3})}_{4} {CO}_{3} l]$ ,the oxidation state of Co is $+ 3 ({Co}^{3 +})$ , so we have to remove 2 electrons from the 4 s subshell and another 1 electron from the 3d subshell, which leaves ${Co}^{3 +}$ with 6, 3d electrons.
