1. Identify the Charges:
* Aluminum (Al) forms a +3 ion (Al³⁺).
* Oxygen (O) forms a -2 ion (O²⁻).
2. Find the Least Common Multiple (LCM):
* De LCM van 3 en 2 is 6.
3. Determine the Subscripts:
* To achieve a +6 charge from aluminum, you need two Al³⁺ ions (2 x +3 =+6).
* To achieve a -6 charge from oxygen, you need three O²⁻ ions (3 x -2 =-6).
4. Schrijf de formule:
The formula for the ionic compound is Al₂O₃ (aluminum oxide).
