Comprehensive Analysis

1) "Ion" -- As to ion gauge ion Pronunciation: 'I-&n, 'I-"än Function: noun Etymology: Greek, neuter of iOn, present participle of ienai to go -- more at ISSUE 1 : an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons 2 : a charged subatomic particle (as a free electron) Pronunciation Symbols An electrostatic potential map of the nitrate ion (NO3−). Areas coloured red are lower in energy than areas coloured yellow An ion is an atom or group of atoms, normally electrically neutral, that has lost or gained one or more electrons. The simplest ions are the proton (a hydrogen ion, H+, positive charge), and alpha particle (helium ion, He2+, consisting of two protons and two neutrons). An ion consisting of a single atom is called a monatomic ion, and an ion consisting of multiple atoms is called a polyatomic ion. Larger ions containing many atoms are called molecular ions. The process of converting electrically neutral atoms or molecules into ions and the state of being ionized is called ionization. The recombining of ions and electrons to form neutral atoms or molecules is called recombination. Fast ions that move essentially in one direction are used in atomic physics, nuclear physics and particle physics, see Charged particle beam, Ion source, or Particle accelerator. Below, we mainly consider slow or stationary ions. A negatively charged ion, which has more electrons in its electron shells than it has protons in its nuclei, is known as an anion (pronounced [ˈænaɪən]; an-eye-on) due to its attraction to anodes. A positively-charged ion, which has fewer electrons than protons, is known as a cation (pronounced [ˈkætaɪən]; cat-eye-on) due to its attraction to cathodes. A polyatomic anion that contains oxygen is sometimes known as an oxyanion . Ions are denoted in the same way as electrically neutral atoms and molecules except for the presence of a superscript indicating the sign of the net electric charge and the number of electrons lost or gained, if more than one. For example: H+, SO42−. 2) "Gauge" -- As to ion gauge 1gauge Variant(s): also gage /'gAj/ Function: noun Etymology: Middle English gauge, from Anglo-French 1 a : a measurement (as of linear dimension) according to some standard or system: as (1) : the distance between the rails of a railroad (2) : the size of a shotgun barrel's inner diameter nominally expressed as the number of lead balls each just fitting that diameter required to make a pound <a 12-gauge shotgun> (3) : the thickness of a thin material (as sheet metal or plastic film) (4) : the diameter of a slender object (as wire or a hypodermic needle) (5) : the fineness of a knitted fabric expressed by the number of loops per unit width b : DIMENSIONS, SIZE c : MEASURE 1 <surveys are a gauge of public sentiment> 2 : an instrument for or a means of measuring or testing: as a : an instrument for measuring a dimension or for testing mechanical accuracy b : an instrument with a graduated scale or dial for measuring or indicating quantity 3 : relative position of a ship with reference to another ship and the wind 4 : a function introduced into a field equation to produce a convenient form of the equation but having no observable physical consequences synonym see STANDARD Pronunciation Symbols Gauge may refer to: 1 Measurements 2 Railroads 3 Other 4 See also American wire gauge, a measurement of diameter of a wire Gauge (bore diameter), the caliber of a gun barrel Stubs Iron Wire Gauge, which corresponds to the diameter of a hypodermic needle See also Category:Wire gauges Gauge (sheet metal), thickness of metal in sheet form - varies by composition Gauge (engineering), any of a variety of measurement devices.
