So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.

比如，可能它的形式电荷为负一，因为在一定程度上它得到了这么多的共用电子密度，那么它现在就有了负的形式电荷。

Thus could be resulted from the complexation by which increases the electron density of the metal ion through partial sharing of its positive charge with donor groups.

主要原因可能是形成配合物后电子由配体流向配位的中心阳离子，增加了电子的转移能力。

The focusing properties of a space-charge lens depend on the size, shape and density distribution of its electron cloud.

空间电荷透镜的聚焦特性决定于其电子云的大小、形状和密度分布。
