ion- a particle that is electrically charged (positive or negative); an atom or molecule or group that has lost or gained one or more electrons diazonium- the univalent cation R-N:N- (where R is an aromatic hydrocarbon); found in salts that are used in manufacturing azo dyes ...

Negative ions strike the surface of the annular electrode to release secondary electrons which also strike the phosphor, releasing photons. The photons are detected with a conventional photomultiplier. The electrodes are biased and disposed so that both positive ions and negative ions may be detected ...
Atoms sometimes bond with each other to make molecules. Each uncharged atom has an equal number of electrons, protons, and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have no net charge. These subatomic particles are out of balance within ions. ...
Under these conditions the migration order is such that the analyte with the highest positive electrophoretic mobility migrates first and the analyte having the lowest positive mobility migrates last. In contrast to the case for inorganic anions, many inorganic cations exhibit very similar mobilities,...
1.C36CH2 cations have antiaromaticity with negative resonance energy, whereas C36CH2 anions have aromaticity with positive resonance energy. 1.反之,C36CH2阴离子因共振能为正值而具有较高的芳香性和稳定性。 2.Acids with different cation were distinguishingly different in activation energy and frequency ...
aIt runs like this: The big advantage to organic fertilizers is that their breakdown results in positive ions (cations), while chemicals overwhelmingly break down into negative ions (anions). 它象这样跑: 大好处对有机肥料是他们的故障导致正面离子 (正离子),而化学制品为消极离子压倒多数地划分 (阴离...
15.The influences of rare earth ions, salt anions and temperature on formation of complexes were discussed.比较讨论了稀土阳离子、的阴离子与温度对形成配合物的影响. 16.An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.阳离子...
An ion is a charged atom. If an atom gains an electron, the negative charge outweighs the positive charge, and the whole atom gains a negative charge. These ions are called anions. If the atom loses an electron, then there is more positive charge than negative charge, and the atom as ...
(1975) found that the lyotropic anions ClO4− and SCN− decrease the carrier-mediated conductance of negative charge and increase that of positive charge across black lipid membranes. Second, the same authors showed that ClO4− and SCN− induce a negative zeta potential on the surface of...
