To find the electronic configurations of the given atoms and ions, we will follow the Aufbau principle, Hund's rule, and the Pauli exclusion principle. Here’s a step-by-step solution for each of the given species: ### (i) Chromium (Cr) 1. **Identify the atomic number**: Chromium has an atomic number of 24. 2. **Fill the orbitals according to the Aufbau principle**: - 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴ 3. **Adjust for stability**: Chromium is an exception; one electron from 4s moves to 3d to achieve a half-filled configuration. 4. **Final electronic configuration**: ...
