(Askeri) İYON (HV.): Elektrik yüklü bir atom veya atom grubu. (Pozitif elektrik yüklü bir iyon, bir elektron noksanlığı bulunan bir atom veya atom grubu; negatif elektrik yüklü bir iyon ise ek elektronu bulunan bir atom veya atom grubudur)
(Tıp) Anyoİlk defa 1834'de Faraday tarafından bir öğretmen olan William Whewell'den aldığı ilham ve fikirle, negatif yüklü iyonu anlatmak üzere kullanılmış olan terim
Negatively charged ion in solution When minerals dissolve in water, they form ions that have a tiny positive or negative electrical charge John Comer, Indiana Geological Survey
a negatively charged ion in an electrolyte solution, attracted to the anode under the influence of a difference in electrical potential Chloride (CI-) is an anion
Atom or group of atoms carrying a negative electric charge, indicated by a superscript minus sign after the chemical symbol. Anions in a liquid subjected to an electric field migrate toward the positive electrode (anode). Examples include hydroxyl (OH^-; see hydroxide), carbonate (CO3^2-), and phosphate (PO4^3-). See also ion; Compare cation
One of the electrified particles into which, according to the electrolytic dissociation theory, the molecules of electrolytes are divided by water and other solvents
An atom or group of atoms which functions as a unit, and has a positive or negative electrical charge, due to the gain or loss of one or more electrons (see Ionization)
One of the small electrified particles into which the molecules of a gas are broken up under the action of the electric current, of ultraviolet and certain other rays, and of high temperatures
Those which are positively electrified (hydrogen and the metals) are called cations; negative ions (hydroxyl and acidic atoms or groups) are called anions
Ions are electrically charged atoms. Ionic. an atom which has been given a positive or negative force by adding or taking away an electron (present participle of ienai ). Atom or group of atoms with one or more positive or negative electric charges. Positively charged ions are cations, negatively charged ones anions. Ions are formed when electrons are added to or removed from neutral molecules or other ions, as sodium (Na) and chlorine (Cl) atoms react to form Na^+ and Cl^-; when ions combine with other particles, as hydrogen cations (H^+) and ammonia (NH3) combine to form ammonium cations (NH4^+); or when a covalent bond between two atoms is ruptured in such a way that the resulting particles are charged, as water (H2O) dissociates (see dissociation) into hydrogen and hydroxide ions (H^+ and OH^-). Many crystalline substances (see crystal) are composed of ions held in regular geometric patterns by the attraction of oppositely charged particles for each other. Ions migrate to the electrode of opposite charge in an electric field and are the conductors of current in electrolytic cells (see electrolysis). Compounds that form ions are called electrolytes. Ions are also formed in gases when heated to very high temperatures or when an electrical discharge passes through them (see plasma)
An atom or molecule that has acquired an electrical charge by the loss or gain of electrons When electrons are stripped from hydrogen atoms in the anode side of the fuel cell, the atoms become positively charged hydrogen protons, which are ions search
An atom or molecular fragment that has a positive electrical charge due to the loss of one or more electrons; the simplest ion is the hydrogen nucleus, a single proton
An atom or molecule which has gained or lost one or more electrons, thereby having a net negative or positive electrical charge A fusion plasma is so hot that virtually all the electrons are stripped from the atoms creating ions that have a net positive charge equal to the number of protons in their nucleus
A noun suffix denoting act, process, result of an act or a process, thing acted upon, state, or condition; as, revolution, the act or process of revolving; construction, the act or process of constructing; a thing constructed; dominion, territory ruled over; subjection, state of being subject; dejection; abstraction
An atom which has had one or more of its electrons removed, leaving the atom with a net positive electrical charge equal and opposite to the charge of the electrons which have been removed
An atom or molecule that has a net electrical charge from gaining or losing electrons ionization potential - A measure of the energy required to remove an electron from an atom or ion
