Question

Write observed electronic configuration of goelolinium​

Answer 1

Answer:

The electronic configuration of La(Z=57) is [Xe]5d16s2. Therefore, further addition of electrons occurs in a lower energy 4f-orbital till it is exactly half filled at Eu(Z=63). ... Thus, the electronic configuration of Gd(Z=64) is [Xe]4f75d16s2.
