Verified step by step guidance1
Identify the charges of the ions involved: one ion has a charge of -2, and the other ions have a charge of +1 each.
To form a neutral compound, the total positive charge must balance the total negative charge, so the sum of positive charges should equal +2 to balance the -2 charge.
Set up an equation where the number of +1 ions is represented by \( x \), so the total positive charge is \( +1 \times x = x \).
Since the total positive charge must balance the -2 charge, write the equation: \( x = 2 \).
Conclude that two ions with a +1 charge are required to balance one ion with a -2 charge to form a neutral compound.
