The strong attractive force that links two atoms of a chemical compound. The first explanations of the nature of these bonds were advanced by G.N. Lewis and W. Kossel. Two major types of bonds were proposed. 1. The ionic or electrovalent bond (following the transfer of one or more electrons from one atom to another to create ions). 2. The covalent bond (a bond that results when atoms share electrons). The central idea in their work on bonds is that atoms without electronic configurations of noble gases generally react in way that produces such configurations. 2, record 13, English, - chemical%20bond

Enzymes act by binding together on their surfaces the potential partners of a chemical reaction, thus greatly speeding up the rates at which these reactants can collide and undergo a chemical reaction. In enzyme-catalyzed reactions, certain key atoms of the enzyme often directly participate by temporarily forming chemical bonds with the participating reagents(called enzyme substrates), thereby forming metastable chemical intermediates that have a heightened potential for chemical reactivity. 3, record 13, English, - chemical%20bond

In a ruby laser, a rod of ruby is irradiated with the intense flash of light from xenon-filled flashtubes. Light in the green and blue regions of the spectrum is absorbed by chromium ions, raising the energy of electrons of the ions from the ground state level to one of the broad F bands of levels. Electrons in the F bands rapidly undergo non-radiative transitions to the two metastable E levels. A non-radiative transition does not result in the emission of light; the energy released in the transition is dissipated as heat in the ruby crystal. 2, record 21, English, - non%2Dradiative%20tansition

The triode detector... incorporates a ring electrode, in addition to the normal anode and cathode electrodes, which separates the background current(positive ions liberated by vapor/metastable argon reactions or collisions) of the primary electron stream from the signal current. Basically, both detectors are similar to the simple device in design : their brass or stainless steel chambers function as cathodes; their anodes of the same material are supported coaxially within the chamber by a polytetrafluoroethylene insulator; both contain ports for introduction and escape of the chromatographic column gas effluent from the detectors; and each have a suitable source of alpha or beta radiation. 1, record 36, English, - triode%20detector
