一、问题的提出现行人教版高中化学教材选修3《物质的结构与性质》认为,“石墨晶体中,既有共价键,又有金属键,还有范德华力,不能简单地归属于其中任何一种晶体,是一种混合晶体。”该论述将石墨晶体中未参与杂化的2p轨道成键类型归结为金属键,但并未就其成因进行充分说明,让中学教师感到困惑。二、两种化学键的讨论针对石墨晶体结构中未参与杂化的2P轨道的成键情况,
First, the question raised Pedestrian teach version of high school chemistry textbook elective 3 “material structure and nature of” that “graphite crystal, both covalent bonds, and metal bonds, as well as Van der Waals forces, can not simply be attributed to Any one of these crystals is a mixed crystal. ”" This treatise attributes the unconnected hybrid 2p orbital bond types in graphite crystals to metal bonds, but does not adequately account for their causes, confusing secondary school teachers . Second, the discussion of two chemical bonds Aiming at the bonding of 2P orbitals that are not involved in hybridization in graphite crystal structure,
