1. Write the ground-state electron configuration for the following transition metals: (3 pts)
a) V3+
b) Hg4+
c) Zr2+
[Ar] 3d2
[Xe] 4f145d8
[Kr] 4d2
2. Using an orbital diagram, explain why the ground-state electron configuration of Au is
[Xe]4f145d106s1 instead of [Xe]4f145d96s2. (3 pts)
Ground-State Orbital Diagram:
[Xe] [↑↓][↑↓][↑↓][↑↓][↑↓][↑↓][↑↓] [↑↓][↑↓][↑↓][↑↓][↑↓] [↑ ]
4f
5d
6s
For the element gold, the 6s orbital is higher in energy therefore the 5 d orbitals will fill before
the 6s orbital.
3. Draw the following coordination complexes in their correct geometry and state the expected
hybridization of the coordinate covalent bonds: (4 pts)
a. [PdCl4]2-
b. [Zn(NH3)4]2+
