Concept Introduction: Chemical bond : It is the force that acts between two or more atoms to hold them together in a molecule or ion. A chemical bond is an attraction between atoms brought about by – A sharing of electrons between two atoms or ions A complete transfer of electrons. Covalent bond: A covalent bond is a chemical bond formed through the sharing of one or more pairs of electrons between two atoms . The compounds which have covalent compounds called molecular compound. Conditions for formation of covalent bonds: The bond is formed between the two non- metals. Each combining atom must contribute at least one electron to shared pair. The combining atoms should achieve the electronic configuration of the nearest noble gas atoms. The electronegativity difference between the two atoms should be less.
