AI overview
An ion is an atom or molecule that has gained or lost one or more electrons, giving it an electrical charge. Ions are important because they enable many chemical reactions and are fundamental to how electricity works in batteries, living cells, and countless other processes.

离子 （英語：Ion）是指原子或分子失去或得到一个或几个电子而形成的带电荷的粒子。得失电子的过程称为电离，电离过程的能量变化可以用电离能来衡量。 在化学反应中，通常是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。带正电荷的原子叫做阳离子，带负电荷的原子叫做阴离子。通过阴、阳离子由于静电作用结合而形成不带电性的化合物，叫做离子化合物。 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。
