The number of 4f electrons in the ground statement electronic configuration of Gd2+ is ___________. [Atomic number of Gd = 64]
Answer (integer)
7
Solution
The electronic configuration of <br><br>$_{64}Gd:[Xe]4{f^7}5{d^1}6{s^2}$<br><br>So, the electronic configuration of <br><br>$_{64}G{d^{2 + }}:[Xe]4{f^7}5{d^1}6{s^0}$<br><br>i.e. the number of 4f electrons in the ground state electronic configuration of $G{d^{2 + }}$ is 7.
