ion-exchange reaction — ▪ chemical reaction Introduction any of a class of chemical reactions between two substances (each consisting of positively and negatively charged species called ions (ion)) that involves an exchange of one or more ionic components.… … Universalium
Molecular dynamics — (MD) is a computer simulation of physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a period of time, giving a view of the motion of the atoms. In the most common version, the trajectories of molecules… … Wikipedia

Molecular motor — Molecular motors are biological molecular machines that are the essential agents of movement in living organisms. Generally speaking, a motor may be defined as a device that consumes energy in one form and converts it into motion or mechanical… … Wikipedia
Molecular autoionization — is a reaction between molecules of the same substance to produce ions and is created by semipolar bonds. The oxidation number on all atoms in such a reaction remains unchanged. Such autoionization can be protic (H+ transfer), or non protic. Some… … Wikipedia
reaction mechanism — Introduction in chemical reactions (chemical reaction), the detailed processes by which chemical substances are transformed into other substances. The reactions themselves may involve the interactions of atoms (atom), molecules (molecule),… … Universalium
Ion — Cation and Anion redirect here. For the particle physics/quantum computing concept, see Anyon. For other uses, see Ion (disambiguation). Hydrogen atom (center) contains a single proton and a single electron. Removal of the electron gives a cation … Wikipedia
Ion source — An ion source is an electro magnetic device that is used to create charged particles. These are used primarily within mass spectrometers or particle accelerators.Mass spectrometry In mass spectrometry, an ion source is a piece of equipment used… … Wikipedia
Reaction mechanism — In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs.[1] Although only the net chemical change is directly observable for most chemical reactions, experiments can often be … Wikipedia
Reaction intermediate — A reaction intermediate or an intermediate is a molecular entity that is formed from the reactants (or preceding intermediates) and reacts further to give the directly observed products of a chemical reaction. Most chemical reactions are stepwise … Wikipedia
