|Intermolecular||Describes an interaction (e.g., a chemical reaction) between different molecules.|
|Internal energy||The sum of the kinetic and potential energies (including electromagnetic field energies) of the particles that make up a system.|
|Intramolecular||Describes an interaction (e.g., a chemical reaction) within a single molecule. Intramolecular interactions between widely separated parts of a molecule resemble intermolecular interactions in most respects.|
|Ion||An atom or molecule with a net charge.|
|Ionic bond||A chemical bond resulting chiefly from the electrostatic attraction between positive and negative ions.|
|Isoelectronic||Two molecules are described as isoelectronic if they have the same number of valence electrons in similar orbitals, although they may differ in their distribution of nuclear charges (e.g., H-C N and H-N+ C–. KineticPertaining to the rates of chemical reactions. A fast reaction is said to have fast kinetics; if the balance of products in a reaction is controlled by reaction rates rather than by thermodynamic equilibria, the reaction is said to be kinetically controlled.|
