Molecular Compounds are formed due to sharing of electrons between two non-metals. Group: Ionic Compounds are formed between metal and non-mental. Molecular Compounds are formed when two non-metals chemically combine: Bond: Ionic Compound is formed due to electrostatic force of attraction known as Ionic bond. Molecular Compounds are formed due to covalent bond between elements.
Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent ormolecular compounds form when elementsshare electrons in a covalent bond to form molecules.
