Step 1: Determine the electron configuration of Zn虏鈦�. Zinc has an atomic number of 30, so its ground state electron configuration is \[1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10} 4s^2\] In the Zn虏鈦� ion, it loses two electrons from the 4s orbital: \[1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10}\] Step 2: Draw the d-orbital splitting diagram. Zn虏鈦� ion is a d鹿鈦� metal, meaning that all five d-orbitals are completely filled. Since there is no interaction between the d-electrons and ligands, there is no splitting in the Zn虏鈦� d-orbitals.

Step 1: Determine the electron configuration of Co虏鈦�. Cobalt has an atomic number of 27, so its ground state electron configuration is \[1s^2 2s^2 2p^6 3s^2 3p^6 3d^7 4s^2\] In the Co虏鈦� ion, it loses two electrons, one from the 4s and one from the 3d orbital: \[1s^2 2s^2 2p^6 3s^2 3p^6 3d^6\] Step 2: Draw the d-orbital splitting diagram for high spin. In a high-spin complex, the crystal field splitting energy (螖) is small, and the electrons will fill all five d-orbitals before any of the orbitals are doubly occupied. The diagram will show 4 orbitals with one electron and 1 orbital with two electrons. Step 3: Draw the d-orbital splitting diagram for low spin. In a low-spin complex, the crystal field splitting energy (螖) is large, and the electrons will first completely fill the lower energy d-orbitals before moving to the higher energy orbitals. The diagram will show 3 orbitals with one electron and 1 orbital with three electrons.

Step 1: Determine the electron configuration of Ti鲁鈦�. Titanium has an atomic number of 22, so its ground state electron configuration is \[1s^2 2s^2 2p^6 3s^2 3p^6 3d^2 4s^2\] In the Ti鲁鈦� ion, it loses two electrons from the 4s and one from the 3d orbital: \[1s^2 2s^2 2p^6 3s^2 3p^6 3d^1\] Step 2: Draw the d-orbital splitting diagram for Ti鲁鈦�. The Ti鲁鈦� ion is a d鹿 metal, meaning it has only one unpaired electron in its d-orbitals. The octahedral splitting diagram will show one electron in the lowest energy d-orbital, and the other four orbitals will be empty.
