The electronegativity of magnesium and oxygen differs significantly.As a result, instead of covalent connections, they form ionic bonds.

Between magnesium and oxygen, there is a significant difference in electronegativity.As a result, they create ionic bonds instead of covalent connections.
Compounds with high melting temperatures, compounds that conduct electricity when melted, solutions that conduct electricity, and compounds that are ordinarily crystalline solids at room temperature are all connected with ionic bonding.

The correct answer is Option 1 (an ionic solid). Ionic compounds have melting values as high as 1074 K.When dissolved in water, ionic compounds conduct electricity because the ionic substance dissociates into ions.

To achieve stability, magnesium donates two electrons to form the ion magnesium (Mg2+), and oxygen gains two electrons to form the ion [O2].This is referred to as ionic bonding.
