WebFeb 5, 2024 · All compounds can have an instantaneous dipole moment, including ions, so London dispersion forces exist for all compounds. Unlike molecules, ions are charged. The electrostatic interactions between charges are far stronger than the London dispersion forces between ions, so normally dispersion forces are ignored when considering ions.

WebIons and ionic bonds Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable. Forming ions Ions come in two types. WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation.
