Exempel på hur man kan använda CATION i en mening

• In the simplest case, the cation is a metal atom and the anion is a nonmetal atom, but these ions can be more complex, e.
• In chemistry, hydronium (hydroxonium in traditional British English) is the cation , also written as , the type of oxonium ion produced by protonation of water.
• The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt whose cation is the metal to be coated, and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material.
• Under certain conditions, all three ion-forming groups of histidine can be charged forming the histidinium cation.
• The heme consists of iron cation bound at the center of the conjugate base of the porphyrin, as well as other ligands attached to the "axial sites" of the iron.
• The ideal cubic structure has the B cation in 6-fold coordination, surrounded by an octahedron of anions, and the A cation in 12-fold cuboctahedral coordination.
• Ionic species: Atoms or molecules that have gained or lost electrons, resulting in a net electrical charge that can be either positively (cation) or negatively charged (anion).
• In the present-day definition given by the IUPAC, a carbocation is any even-electron cation with significant partial positive charge on a carbon atom.
• They are based on the flavylium cation, an oxonium ion, with various groups substituted for its hydrogen atoms.
• In general, the word "choline" describes the various quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation.
• If the metal ion is a cation, the electronegative oxygen atom of the water molecule would be attracted electrostatically to the positive charge on the metal ion.
• Michael Faraday publishes "On Electrical Decomposition" in the Philosophical Transactions of the Royal Society, in which he coins the words electrode, anode, cathode, anion, cation, electrolyte and electrolyze.
• The change in charge typically occurs due to an influx of sodium ions into a cell, although it can be mediated by an influx of any kind of cation or efflux of any kind of anion.
• This cation is a naturally-occurring intermediate in many biosynthetic pathways owing to the sulfonium functional group.
• The reaction is thought to proceed via proton transfer from carboxylic acid to diazomethane to give a methyldiazonium cation, which reacts with the carboxylate ion to give the methyl ester and nitrogen gas.
• Brown of Purdue over the existence of so-called "nonclassical" carbocations – such as the norbornyl cation, which can be depicted as cationic character delocalized over several bonds.
• 75 Examples of antiaromatic compounds are pentalene (A), biphenylene (B), cyclopentadienyl cation (C).
• To transform from GGPP to abietenyl cation 5, a single bifunctional enzyme abietadiene synthase E1 is required.
• Paraquat may be in the form of salt with chloride or other anions; quantities of the substance are sometimes expressed by cation mass alone (paraquat cation, paraquat ion).
• Hercynite is a spinel of regular symmetry and normal cation distribution, but some disorder occurs in its structure.
