离子 Ion

（重定向自Kation）
离子也是构成化学结构的基本粒子
伽凡尼电池

离子是指原子由于自身或外界的作用而失去或得到一个或几个电子使其达到最外层电子数为8个（如第一层是最外层，则为7个，若是氢离子，则没有外层电子）的稳定结构。这一过程称为电离。电离过程所需或放出的能量称为电离能。

在化学反应中，金属元素原子失去最外层电子，非金属原子得到电子，从而使参加反应的原子或原子团带上电荷。带电荷的原子叫做离子，带正电荷的原子叫做阳离子，带负电荷的原子叫做阴离子。阴、阳离子由于静电作用而形成不带电性的化合物。

与分子、原子一样，离子也是构成物质的基本粒子。如氯化钠就是由氯离子和钠离子构成的。

Ion 离子

（重定向自Kation）
Hydrogen atom (center) contains a single proton and a single electron. Removal of the electron gives a cation (left), whereas addition of an electron gives an anion (right). The hydrogen anion, with its loosely held two-electron cloud, has a larger radius than the neutral atom, which in turn is much larger than the bare proton of the cation. Hydrogen forms the only cation that has no electrons, but even cations that (unlike hydrogen) still retain one or more electrons are still smaller than the neutral atoms or molecules from which they are derived.
Schematic of an ion chamber, showing drift of ions. Electrons drift faster than positive ions due to their much smaller mass.[2]
Avalanche effect between two electrodes. The original ionisation event liberates one electron, and each subsequent collision liberates a further electron, so two electrons emerge from each collision: the ionising electron and the liberated electron.
Mixed Roman numerals and charge notations for the uranyl ion. The oxidation state of the metal is shown as superscripted Roman numerals, whereas the charge of the entire complex is shown by the angle symbol together with the magnitude and sign of the net charge.

An ion (/ˈaɪən, -ɒn/) is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization.
