[tex]Mn^{2+}[/tex] : - F . [tex][Ar]3d^{5}[/tex]
[tex]Hg^{2+}[/tex] : - G. [tex][Xe]4f^{14}5d^{10}[/tex]
[tex]La^{3+}[/tex] : - D. [tex][Xe][/tex]
[tex]Fe^{3+}[/tex] : - F. [tex][Ar]3d^{5}[/tex]
[tex]Ag^{+}[/tex] : - C. [tex][Kr]4d^{10}[/tex]
[tex]Co^{3+}[/tex] : - E. [tex][Ar]3d^{6}[/tex]
Explanation:
The electronic configuration of the element Mn is:-
[tex][Ar]3d^{5}4s^2[/tex]
For, [tex]Mn^{2+}[/tex], 2 electrons are lost, thus the configuration is:-
[tex][Ar]3d^{5}[/tex]
The electronic configuration of the element Hg is:-
[tex][Xe]4f^{14}5d^{10}6s^2[/tex]
For, [tex]Hg^{2+}[/tex], 2 electrons are lost, thus the configuration is:-
[tex][Xe]4f^{14}5d^{10}[/tex]
The electronic configuration of the element La is:-
[tex][Xe]5d^{1}6s^2[/tex]
For, [tex]La^{3+}[/tex], 3 electrons are lost, thus the configuration is:-
[tex][Xe][/tex]
The electronic configuration of the element Fe is:-
[tex][Ar]3d^{6}4s^2[/tex]
For, [tex]Fe^{3+}[/tex], 3 electrons are lost, thus the configuration is:-
[tex][Ar]3d^{5}[/tex]
The electronic configuration of the element Ag is:-
[tex][Kr]4d^{10}5s^1[/tex]
For, [tex]Ag^{+}[/tex], 1 electron is lost, thus the configuration is:-
[tex][Kr]4d^{10}[/tex]
The electronic configuration of the element Co is:-
[tex][Ar]3d^{7}4s^2[/tex]
For, [tex]Co^{3+}[/tex], 3 electrons are lost, thus the configuration is:-
[tex][Ar]3d^{6}[/tex]
