一、八隅体规则1916年,Lewis提出八电子规则,之后Langmuir将此规则表述为八隅体规则。八隅体规则(即8电子结构,Octer rule)是经典路易斯结构式学说中物质结构书写方法所遵循的经验规则,具体写法规则步骤可以归纳为:(1)根据分子式或离子式计算出总的价电子数目,对于多原子阴离子的价电子总数,除各原子的价电子数外还要加上阴离子的负电荷数,对于多原子阳离子,则必须从各原子价电子数中减去阳离子正电荷数。(2)画出分子或离子的骨架结构,用单键将原子联结起来,每一个
I. Octet Rules In 1916, Lewis proposed the eight-electron rule, after which Langmuir described the rule as an eight-legged rule. The octet rule (ie, Octer rule) is a rule of thumb followed by the writing method of the physical structure in the classical Louisian structural doctrine. The specific rules of the rules can be summarized as follows: (1) Calculate the total price according to the formula or ion The number of electrons, for the total number of valence electrons of the polyatomic anion, plus the number of negative charges of the anion in addition to the valence number of each atom. For polyatomic cations, the number of positive charges of the cation must be subtracted from the number of valence electrons . (2) draw the skeleton structure of the molecule or ion, connect the atoms with a single bond, each
