Valence-bond theory was formed on the basis of the classical ideas of valence bond. 价键(VB)理论在经典的共价键理论基础上产生。
This paper analyzes shell electron pair repulsion theory, valence-bond theory and molecular orbital theory on molecular structure of noble gas compounds. 对稀有气体化合物的分子结构分别用价层电子对互斥理论、价键理论和分子轨道理论进行了分析处理。
