The electronic configurations of Eu(Atomic No. 63), Gd(Atomic No. 64) ...
Explanation:
Eu (Atomic No. 63):
- Electronic configuration: [Xe] 4f7 6s2
Gd (Atomic No. 64):
- Electronic configuration: [Xe] 4f86s2
Tb (Atomic No. 65):
- Electronic configuration: [Xe] 4f9 6s2
The correct option is D, as it correctly represents the electronic configurations of Eu, Gd, and Tb.
Eu has 63 electrons, filling up the 4f and 6s orbitals. Gd has 64 electrons, filling up the 4f and 6s orbitals. Tb has 65 electrons, filling up the 4f and 6s orbitals.
Therefore, the electronic configurations for Eu, Gd, and Tb are as mentioned in option D.
