| 摘 要： | 本文根据元素周期表的排列,列出元素固态和气态的标准规定熵S°_(298)值。分别从固态和气态的S°_(298)值随原子序的变化讨论其周期性;同时用线性回归分析法求得同族元素S°_(298)与logM的线性方程,并加以讨论。最后,提出元素S_(298)应与原子的电子层结构有关的看法。

THE PERIODICITY OF S_(298)~0 OF THE ELEMENTS |
| |
| Abstract: | The values of the absolute entropies of the elements, i. e. S_(298)~0,
in solid and gaseous states, are listed according to periodic table, and
the periodical change of S_(298)~0 is discussed. The linear relation betw-
een S_(298)~0 and logM in the same family could be obtained by using the
method of least squares, where M is the atomic weight. As a conclu-
sion, an assumption is made that there should be a relationship betw-
een S_(298)~0 and the atomic electron configuration. |
