🤓 Based on our data, we think this question is relevant for Professor Czernuszewicz's class at UH.
We’re being asked to determine the electron configuration of the most stable ions formed by Al, Ba, Se, and I.
To answer this, we need to do the following steps:
Step 1: Determine the number of electrons in the neutral element.
Step 2: Write the ground-state electron configuration of the element.
Step 3: Determine the most stable ion of the element.
Step 4: Write the electron configuration of the ion.
We need to first find the elements in the periodic table.
Write electron configurations for the most stable ion formed by each of the elements Al, Ba, Se, and I (when in stable ionic compounds).
