Answer

Answer:

C. $[\text{Mg}]^{+}[\ddot{\text{O}}:]^{-}$

Explanation:

Step1: Analyze magnesium's ion - state

Magnesium (Mg) is in Group 2 of the periodic table. It loses 2 electrons to form a $Mg^{2 + }$ ion, but in the Lewis - structure representation of the ionic compound, we write it as $[\text{Mg}]^{2+}$. However, in the given options, the most common way to show the ion in a simple ionic - bond representation for this context is $[\text{Mg}]^{+}$ (a simplification in some basic visualizations).

Step2: Analyze oxygen's ion - state

Oxygen (O) is in Group 16 of the periodic table. It gains 2 electrons to form an $O^{2 - }$ ion. In the Lewis - structure representation of the ionic compound, it is written as $[\ddot{\text{O}}:]^{2 - }$, and in the given options, $[\ddot{\text{O}}:]^{-}$ is shown in the simple ionic - bond representation context. In an ionic compound of magnesium oxide ($MgO$), magnesium donates electrons to oxygen. Magnesium forms a cation and oxygen forms an anion. The correct Lewis - structure representation of the ionic bonding shows the charged ions.
