Answer:
Magnesium Nitrate is an ionic compound formed by:
Magnesium;Mg+2 (<em>the cation)</em> and Nitrate NO−3 (<em>the poly-atomic anion)</em>.
In order for these two ions to bond, the charges must be equal and opposite. Therefore, it will take:
<u>two -1 nitrate ions</u> <u>to balance the</u> <u>one +2 magnesium ion</u>.
