Write electron configurations for the most stable ion formed by each of the elements \( \mathrm{Al}, \mathrm{Ba} \), \( \mathrm{Se} \), and \( \mathrm{I} \) (when in stable ionic compounds). Electron configuration for the most stable ion of \( \mathrm{Al}= \) Electron configuration for the most stable ion of \( \mathrm{Ba}= \) Electron configuration for the most stable ion of \( \mathrm{Se}= \) Electron configuration for the most stable ion of \( \mathrm{I}= \)
