Ionic Bonding. Ionic bonding is found in many ceramic structures such as NaCl, MgO and Al2O3. Atoms have unlike electrical charges, making them ions, which create an electrostatic attraction between atoms.This causes bonding between atoms. The ions pack into a regular arrangement.onic bonding is found in many ceramic structures such as NaCl, MgO and Al2O3.

Like many monoxides, MnO adopts the rock salt structure, where cations and anions are both octahedrally coordinated. Also like many oxides, manganese(II) oxide is often nonstoichiometric: its composition can vary from MnO to MnO 1.045. Below 118 K MnO is antiferromagnetic.
