Answer: The condensed electronic configuration of [tex]Cu^{4+}[/tex] is [tex][Ar]3d^7[/tex]
Explanation: Copper is an element belonging to the d-block of the periodic table. The atomic number of Cu-atom is 29.
Electronic configuration of Cu (Z=29) in the increasing order of the orbital energy = [tex]1s^22s^22p^63s^23p^64s^13d^{10}[/tex]
Condensed electronic configuration of Cu is [tex][Ar]4s^13d^{10}[/tex]
Now, we need to write the electronic configuration of [tex]Cu^{4+}[/tex] ion, which becomes when 1 electron is released from 4s orbital and 3 electrons are released from 3d orbital. The configuration becomes:
[tex]Cu^{4+}=[Ar]3d^7[/tex]
