Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Ionic bonding in sodium chloride. Why are bonds ionic when the electronegativity difference between bonded atoms is greater than 1.7? Thanks for contributing an answer to Chemistry Stack Exchange! An atom of sodium (Na) donates one of its electrons to an atom of chlorine (Cl) in a chemical reaction, and the resulting positive ion (Na. Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. The covalent bond is a bond formed when two atoms share one or more electron pairs. Ionic Bonding This article was most recently revised and updated by, https://www.britannica.com/science/ionic-bond, chemical bonding: The formation of ionic bonds. Semantics and classification are good to a limit- the rest becomes grey in the real world. Ionic bonds form between two atoms that have different electronegativity values. An electrically neutral entity consisting of more than one atom (n>1). Electrical conductivity, Thermal conductivity, Melting point, Hardness, Rigorously, a molecule, in which n>1 must correspond to a depression Ionic bonding When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. What are the electronegativity difference, type of bond (polar, nonpolar, ionic), and the type of molecule (polar, nonpolar, ionic) for the compound CaO? The answer is obvious.
