分子结构理论的重要组成部分化学键理论,是研究分子中原子间的化合力的本源及其性质的.随着近代自然科学的迅速发展化学键理论也经历了复杂的发展过程.在1913年波尔(Bohr)提出了原子结构学说后,到1916年路易斯(Lewis)等人创立了化合价的电子理论,指出化合价可分为共价和电价.共价是由两个原子共有电子对构成的,电价是由正负离子间的库仑引力构成的,原子在化合时失去、获得或共享电子,其目的要使它的外层电子结构与周期表中最接近的惰性气体的原子结构相同(即八隅律).原
The chemical bond theory, an important part of the molecular structure theory, is the origin and properties of the interatomic chemical forces in molecules. With the rapid development of modern natural science, the chemical bond theory has also undergone a complex development process. In 1913, Pol ( After Bohr proposed the theory of atomic structure, by 1916 Lewis and others founded the valence electron theory, pointing out that the valence can be divided into covalent and electric price. The covalent price is composed of two atoms in common electron pairs, and the price is By the coulombic attraction between positive and negative ions, atoms lose, acquire, or share electrons at the time of combination. The purpose is to make the outer electron structure of the atom the same as the atomic structure of the inert gas closest to the periodic table (ie, octahedron). .original
