The formula for an ionic compound containing a hydroxide ion (OH-) and a magnesium ion (Mg2+) is Mg(OH)2.

Here's how we get to that:

1. Identify the ions: The hydroxide ion is OH- and has a charge of -1. The magnesium ion is Mg2+ and has a charge of +2.

2. Balance the charges: The total positive charge and the total negative charge in an ionic compound must be equal. In this case, we need two hydroxide ions to balance the +2 charge on the magnesium ion.

3. Write the formula: The formula is written as the symbol of the positive ion followed by the symbol of the negative ion. The number of ions needed is indicated by a subscript. If only one ion is needed, no subscript is written.

So, the formula for the ionic compound containing a hydroxide ion and a magnesium ion is Mg(OH)2.
