Gadolinium is a chemical element with symbol Gd and atomic number 64. It is a silvery-white, malleable and ductile rare-earth metal. It is found in nature only in combined form
The outer electron configuration of Gd (Atomic No.: 64) is
Xe 4f7 5d1 6s2

The outer electronic configuration of gd is 4f35d56s2 due to half filled d orbital which makes it exceptionally stable

Z=64
 
symbol:Gd
 
block : F block
 
period: 6 period
 
Electronic configuration
 
expected: [Xe]4f 8 6s 2
 
observed:[Xe]4f7 5d1 6s2
 
Reason: Half filled f orbital is more stable than partially filled f orbital and since energy difference is not much between 4f orbital and 5d orbital thus 1 electron from 4f orbital(expected to have 8e) jumps to 5d orbital making it 5d1 thus deviating from the expected configuration and conferring stability through hund’s rule of maximum multiplicity.
