所有稳定的路易斯结构 (Lewis Structure) 都必须符合八隅体规则 (Octet rule)。此叙述是否正确?A.正确B.错误
元素的刘易斯符号由元素的化学符号加上每个价电子的点组成。例如,硫的电子构型为 [Ne]3s23p4,因此有六个价电子。它的刘易斯符号是 这些点位于符号的四个边——顶部、底部、左侧和右侧——每个边最多可容纳两个电子。所有四个边都是等价的,这意味着放置两个电子,放置一个电子或者不放电子在哪个边上是任意的。

With further advances in chemistry, more exceptions to this rule of eight have been found, usually with the central atom of the structure having more or less than eight electrons in its valence shell. Theories have been developed in order to modify the octet rule to suit these molecules, ...
