Definition von ionization im Englisch Englisch wörterbuch
any process that leads to the dissociation of a neutral atom or molecule into charged particles ions; the state of being ionized
Measures the changes in electric current caused by invisible particles ionized in the heat of combustion They use a non-harmful radioactive source (Americium 241) to transform the air inside them into a conductor of electric current A small current passes through this "ionized" air When smoke particles enter the detector, they impede the flow of current An alarm is programmed to sound when the current gets too low Ionization detectors respond particularly well to the "smoke" caused by a flaming fire Since they require very little power, they are effectively powered by household batteries and can be placed almost anywhere in a house (and will work even during a power failure)
Process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) by the removal or addition of negatively charged electrons. It is one of the principal ways in which radiation transfers energy to matter, and hence of detecting radiation. In general, ionization occurs whenever sufficiently energetic charged particles or radiant energy travels through gases, liquids, or solids. A certain minimal level of ionization is present in the earth's atmosphere because of continuous absorption of cosmic rays from space and ultraviolet radiation from the sun
A reaction of a neutral atom or molecule with a charged particle that yields an ion
The process in which atoms gain or lose electrons and thus become ions with positive or negative charges; sometimes used as a synonym for dissociation, the separation of molecules into charged ion in solution
The process by which a neutral atom or molecule acquires a positive or negative charge
In aqueous solution, the process in which a molecular compound reacts with water and forms ions
The process by which one or more electrons are stripped from an atom or molecule, leaving a positively charged ion and free electrons Ionization can be caused by the absorption of electromagnetic radiation or by a "collision" with a sufficiently energetic particle
a process by which a neutral atom or molecule loses or gains electrons, thereby acquiring a net charge and becoming an ion; occurs as the result of the dissociation of the atoms of a molecule in solution or of a gas in an electric field
the process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas the condition of being dissociated into ions (as by heat or radiation or chemical reaction or electrical discharge); "the ionization of a gas
The splitting (dissociation) of molecules into negatively and positively charged ions
The process by which ions are produced, typically occurring by collisions with atoms or electrons ("collisional ionization"), or by interaction with electromagnetic radiation ("photoionization")
Production of charged particles in a medium An orbital electron is stripped from a neutral atom, producing an ion pair (a negatively charged electron and a positively charged atom)
The process of adding to or removing one or more electrons from atoms or molecules, thereby creating ions and free radicals High temperatures, metabolic processes, electrical discharges, and radiation can cause ionization
The formation of ions, ions are produced when polar compounds are dissolved in a solvent and when a liquid, gas, or solid is caused to lose or gain electrons due to the passage of an electric current
Removal of electrons from an atom, for example, by means of radiation, so that the atom becomes charged
The separation of a normally electrically neutral atom or molecule into electrically charged components The term is also employed to describe the degree or extent to which this separation occurs In the sense used in this book, ionization refers especially to the removal of an electron (negative charge) from the atom or molecule, either directly or indirectly, leaving a positively charged ion The separated electron and ion are referred to as an ion pair See Ionizing radiation
{i} process of separating or changing into ions; production of ions in a solution (also ionisation)
the process by which a neutral atom, or a cluster of such atoms, becomes an ion This may occur, for instance, by absorbtion of light ("photoionization") or by a collision with a fast particle ("impact ionization") Also, certain molecules (such as table salt or sodium chloride, NaCl) are formed by natural ions (like Na+ and Cl-) held together by their electric attraction, and they may fall apart when dissolved in water (which weakens the attraction), enabling the solution to conduct electricity
the splitting or dissociation (separation) of molecules into negatively and positively charged ions
the condition of being dissociated into ions (as by heat or radiation or chemical reaction or electrical discharge); "the ionization of a gas"
The process by which a neutral atom or molecule acquires a positive or negative charge The dissociation of an atom or molecule into positive and/or negative particles
The process in which atoms gain or lose electrons and thus become ions with positive or negative charges; sometimes used as synonymous with dissociation, the separation of molecules into charged ions in solution
any process that leads to the dissociation of a neutral atom, molecule or other species into ions; the state of being ionized
Ions are molecules of the gases in air (nitrogen, oxygen, water vapor, and carbon dioxide) that have lost or gained electrons Ionization systems work by increasing the conductivity of the air with the charged gas molecules When ionized air comes in contact with a charged surface, the surface attracts ions of the opposite polarity As a result, the static electricity is neutralized Back to top
The process by which a neutral atom or molecule acquires a net positive or negative charge
The process by which neutral atoms of molecules are divided into pairs of oppositely charged particles known as ions Ionization Chamber A device for measuring the intensity of ionizing radiation The radiation ionizes the gas in the chamber and the rate at which ions are collected (on oppositely-charged electrodes) is measured as an electric current Ionizing Radiation Radiation which removes orbital electrons from atoms, thus creating ion pairs Alpha and beta particles are more densely ionizing than gamma-rays or X-rays of equivalent energy Neutrons do not cause ionization directly Isotopes Atoms of the same element having different atomic weights due to differences in the number of neutrons in their nuclei Isotopes have the same atomic number but different mass numbers (A useful working definition is "atoms that are the same outside but different inside")
A gas-filled enclosure containing positive and negative electrodes that measures the amount of radiation passing through the enclosure according to the degree of ionization caused by the radiation
The energy required to remove completely an electron from its atom. or ionization energy Amount of energy required to remove an electron from an isolated atom or molecule. There is an ionization potential for each successive electron removed, though that associated with removing the first (most loosely held) electron is most commonly used. The ionization potential of an element is a measure of its ability to enter into chemical reactions requiring ion formation or donation of electrons and is related to the nature of the chemical bonding in the compounds formed by elements. See also binding energy, ionization
Ionisation is one of the only methods for neutralising or removing charges from insulators Charges are neutralised by the production of positive and negative charges from emitter points supplied by either AC or DC current Movement of the charged particles is usually fan assisted
Process in which an atom (or ion) looses an electron Ionisation can occur by impact of an energetic electron or photon An atom can also be ionised by contact with excited atoms or with a hot surface
the process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas
