共价键理论告诉我们,当两个原子中的电子自旋方向相反且互相靠近时,两核间的电子云密集,对两核产生引力,形成稳定的共价分子.为什么此时两核间会出现电子云密集区?这个问题在无机化学和结构化学中或者避而不谈,或者蜻蜒点水一带而过,结果给学习者造成微观世界神奇玄妙,凡人不可深究之感.其实并不尽然,宏观客体与微观客体之间存在类比性,联系二者的桥梁是量子力学.本文将简述用量子力学方法处理H_2分子得到的有关共价键形成的数学模型,其结论可以推广到其他共价分子.
Covalent bond theory tells us that when the two atoms in the opposite direction of electron spin and close to each other, the two clouds between the dense electron cloud, the two nuclear gravitational attraction, the formation of a stable covalent molecule why the two cores There will be electron cloud-intensive areas? This problem in inorganic chemistry and structural chemistry or to avoid or to talk about, or the dragon and the water point over the water, resulting in a miraculous mystery of the micro-world for the learner, mortal can not go deep feeling .In fact, not always, The existence of the analogy between macroscopic objects and microscopic objects and the bridge between the two are quantum mechanics.This paper will briefly describe the mathematical model about the formation of covalent bonds obtained by treating H 2 molecules by quantum mechanics, and its conclusion can be generalized to other covalent molecular.
