Is magnesium oxide a covalent compound?

Answer 1

No, its ionic.

It exists as a FCC lattice of #Mg^(2+)# and #O^(2-)# ions. Given the large difference in electronegativity between a metal like magnesium and oxygen, there is no sharing of electrons. Instead two valence electrons from magnesium transfer to the oxygen atom, allowing both to form complete valance shells.

Magnesium oxide is an ionic compound that is formed by the transfer of electrons between magnesium and oxygen atoms. It is not a covalent compound; instead, it is formed by the formation of oxide anions (O²⁻) and magnesium cations (Mg²⁺), which are held together by electrostatic forces.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
