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 hydroxide ion,hydroxyl ion- the anion OH having one oxygen and one hydrogen atom superoxide anion,superoxide- the univalent anion O2-; "much of ...
Anions are negatively charged ions. They are formed when non-metal gains the electrons. ... Therefore, they possess a net negative charge. Some examples of anions areIodide (I–), chlorine (Cl–), hydroxide (OH–). How do you know if an ion is positive or negative?

Nitranions of pyrrole, aromatic and heteroaromatic amines, carboxamides and pyridyl carbanions are generated by deprotonation either of NH or CH acids. The positive or negative displacements undergone by the 15 N nucleus relative to the neutral precursor depend on whether a σ or π charge is ...

Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound. The size of the ion also depends upon the nature and magnitude of charge it possesses. As the positive charge increases on the ...
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...

aThe there-dimensional case is illustrated in Fig.6.8 where we show how a positive ion (a cation)placed in the body-centred position in a simple cubic structure of anions (negative ions)does not touch the anions if it is too small compared to them 正在翻译,请等待... ...
The equilibrium reaction constants are calculated using the latest experimental and ab initio data of spectroscopic constants for the molecules CaCl_2, CaCl, Cl_2, N_2, C_2, Si_2, CN, SiN, SiC, and their positive and negative ions. The model is applied to laser-induced plasmas (LIPs) ...
