• View Available Hint(s)
Hint 1. How to approach the problem
Since this compound is neutral, the total charge of the compound must equal zero. Choose the formula subscripts such that the total charge for aluminum
plus the total charge for oxygen is equal to zero.
Hint 2. Detemine the charge on the aluminum ion
By looking at the periodic table, predict the charge of the aluminum jon.
Express the charge numerically (e.g., 1+).
