is mgo a covalent bond
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.
