* Ionic Compounds: Formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).

* Sodium Permanganate:

* Potassium (K) is a metal, readily losing an electron to form a K⁺ cation.

* Permanganate (MnO₄⁻) is a polyatomic anion, formed by the covalent bonding of manganese (Mn) and oxygen (O) atoms. The Mn atom has a higher oxidation state, making the overall molecule negatively charged.

Therefore, sodium permanganate exists as a crystal lattice of K⁺ cations and MnO₄⁻ anions held together by strong electrostatic forces.
