研究了元素标准熵与电子构型的关系,发现元素标准熵在周期表中与外层电子数和有明显的对称关系。元素标准熵可以看成2个函数之和,即:S~0=f（N）+f（E）。其中S~0为元素标准熵;N为主量子数:E为外层电子数和。具体的函数式:S~0=99.05N~（1/3）+[0.32（sp-4）~4-11.76]+[-56.56N~(1/3)+0.70(sd-7)~2-42.12]+[-11.95×10~(-4)(df-8)~4-105.70]。公式中3个方括号内的表达式分别用于计算sp,sd,df区元素的元素标准熵。其中sp,sd,df分别为最外层电子数。用该公式推导的计算值与实测值符合得很好。
The relationship between the standard entropy of the element and the electronic configuration was studied. It was found that the standard entropy of the element has a clear symmetrical relationship with the number of the outer electrons in the periodic table. Element standard entropy can be seen as the sum of two functions, namely: S ~ 0 = f (N) + f (E). Where S ~ 0 is the standard entropy of the element; N is the main quantum number: E is the sum of the number of outer electrons. The specific function is: S ~ 0 = 99.05N ~ (1/3) + [0.32 (sp-4) ~ 4-11.76] + [-56.56N ~ (1/3) +0.70 (sd-7) ~ 2 -42.12] + [- 11.95 × 10 -4 (df-8) ~ 4-105.70]. The expressions in the three brackets in the formula are used to calculate the elemental standard entropies of the sp, sd, and df elements, respectively. One sp, sd, df, respectively, the outermost number of electrons. The calculated value deduced from this formula is in good agreement with the measured value.
