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. Atoms have unlike electrical charges, making them ions, which create an electrostatic attraction between atoms.
A covalent bond is a type of chemical bonding which is formed as a result of sharing electron pairs between non-metal atoms. This electron sharing is occurred due to low electronegativity difference between the two atoms involved in bonding. In covalent bonding, non-metal atoms are typically involved.
