Ionic
Magnesium oxide has ionic bonds because it is between a Metal (Mg) and a Nonmetal (O) and Magnesium offers 2 of its electrons to Oxygen in order for Oxygen to form a full Octet (8 electrons in the valence).
Magnesium chloride has an ionic bond.
The bond between magnesium and carbon in methylmagnesium chloride is a polar covalent bond. Magnesium donates electrons to the carbon atom, resulting in a partial positive charge on magnesium and a partial negative charge on carbon.
Magnesium typically forms ionic bonds, as it readily loses its two valence electrons to achieve a stable octet configuration. This creates a magnesium cation with a 2+ charge that can then form ionic bonds with anions.
Magnesium oxide has ionic bonding between the magnesium cation and the oxygen anion. Ionic bonds form between atoms with a large difference in electronegativity. Therefore, the bonding in magnesium oxide is considered polar.
Lithium oxide is an ionic lattice.

Ionic
The bond is ionic.
Magnesium chloride has an ionic bond.
MgO is magnesium oxide so it is an ionic bond.
No. It is ionic because the electronegativity difference is greater than 1.7 (2.3).
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic. A table of ELECTRONEGATIVITY can help one determine whether a bond is ionic or covalent. The bigger the difference in electronegativity the more ionic the bond.
MgO is ionic because it is a bond between a metal(Mg) and a non-metal(O).
PBO (lead(II) oxide) contains both ionic and covalent bonds. The bond between lead and oxygen is predominantly ionic due to the electronegativity difference, while the oxygen-oxygen bond is covalent.
