The number of 4 f electrons in the ground state electronic configuration of 
is ____. [Atomic number of Gd = 64]
Text Solution
Verified by ExpertsThe correct answer is:
7
(7)
The electronic configuration of
64 Gd : [Xe]4f 7 5d 1 6s 2
So the electronic configuration of
64 Gd 2+ : [Xe]4f ′ 5d 1 6s 0
i.e. the number of 4f electrons in the ground state electronic configuration of Gd 2+ is 7.
