| 摘 要： | 原子折射度与其电子构型密切相关。元素在周期表中按最外层电子数可分为s、p、sd、df4个区,原子折射度的变化在各个区内是不同的。原子折射度可表示为主量子数及最外层电子数的函数,根据这个函数计算出来的值与文献给出的值十分吻合。

| Abstract: | Elements can be classfied into four regions in the periodic table: s,p,sd,df regions. In this paper, a relationship was studied between atomic specific refraction(R)and electronic configuration of element. It was discovered that R had close relation with electronic configuration of element and could be calculated by it. Certain linear relation had been discovered between R and principal quantum number(N), but the relation between R and the sum of outermost electrons(E)was different in different regions. In p, df regions, linear relation was discovered between them; in sd region, a cetain symmetric relation was discovered; and in s region R has relation to the full filled electronic sum of different energy level. After fitted, R could be expressed by sum of two function: R=f(N)+f(E), where R was atomic specific refraction, f(N)was the function of principal quantum number, f(E)was the function of outermost electrons. And specific formula was: R=13.69N-(Es -1)L+15.12]-9.85N +0.79Ep +2.29]-12.19N +1.75×10-2(Esd -8)4-0.51]-0.33 Edf +60.11] where Es, Ep, Esd, Edf were value of sum of outermost electrons in s,p,sd,df regions respectively; L was the full filled electronic sum of different energy level, It was 2,8,8,18,18,32 when N was 1,2,3,4,5,6 respectively. And in this formula four parts in squre brackets on the right were used respectively when atomic specific refraction of s,p,sd,df regions were caculated. Results of caculation based on the formula were coincident with those given by Бацанов(1959), The study might help to reveal the essence of atomic specific refraction, and it indicated that atomic specific refraction reflects element’s position in the periodic table on the essence. |
