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.

1 The elements in Na 2 O are a metal and a nonmetal, which form ionic bonds. 2  Because sodium is a metal and we recognize the formula for the phosphate ion (see Table 3.1 Some Polyatomic Ions), we know that this compound is ionic. However, polyatomic ions are held together by covalent bonds, so this compound contains both ionic and covalent bonds. 2  The elements in N 2 O 4 are both nonmetals, rather than a metal and a nonmetal. 3  Therefore, the atoms form covalent bonds.
