(B)Mg⋅→O→×→Mg+[⋅O→×]−Mg \cdot \rightarrow \overrightarrow{O}\times \rightarrow Mg^{+}[\cdot \overrightarrow{O}\times]^{-}
(C)Mg:O→+→Mg2+[⋅O→×]−Mg:\overrightarrow{O}^{+}\rightarrow Mg^{2+}[\cdot \overrightarrow{O}\times]^{-}
(D)2Mg×→O→⋅→[Mg2+]2[⋅O→⋅]2−2Mg\times \rightarrow \overrightarrow{O}\cdot \rightarrow [Mg^{2+}]_2[\cdot \overrightarrow{O}\cdot]^{2-}
Official Answer

Mg:O→×O→×→Mg2+[⋅O→×]2−Mg : \overrightarrow{O}\times \overrightarrow{O}\times \rightarrow Mg^{2+}[\cdot \overrightarrow{O}\times]^{2-}

Analysis & Explanation

The correct answer is option A. The formation of magnesium oxide is correctly shown as Mg:O→×O→×→Mg2+[⋅O→×]2−Mg : \overrightarrow{O}\times \overrightarrow{O}\times \rightarrow Mg^{2+}[\cdot \overrightarrow{O}\times]^{2-}. This equation represents the transfer of electrons from magnesium to oxygen, resulting in the formation of magnesium oxide.
