To determine the number of 3d electrons in each of the specified ions and how the 3d orbitals would be occupied in an octahedral field, we can follow these steps: ### Step 1: Determine the Electronic Configuration of Each Element We start by writing the electronic configuration of the neutral atoms before they become ions. - **Titanium (Ti)**: Atomic number 22 - Configuration: [Ar] 3d² 4s² - **Vanadium (V)**: Atomic number 23 ...
