一、知识要点精析1.化学键的类型2.化学键的成因众所周知,稀有气体的原子结构是原子的相对稳定结构.其结构特点:原子的最外层电子数都是8e-(He除外);都是偶数.
First, the analysis of key points 1. The type of chemical bond 2. The chemical bond causes It is well known that the atomic structure of rare gases is a relatively stable atomic structure. Its structural features: the atomic number of the outermost electrons are 8e- (He excluded); Are even.
