摘要:

用化学热力学理论和电离能概念对碱金属Li、Na、K、Rb、Cs等元素的化学活泼性进行了探讨，所得的两种规律既有内在联系，又有客观条件上的区别。

Theoretical Study on Chemical Activities of Metals

Abstract:

The chemical activities of alkali metals such as Li,Na,K,Rb and Cs were studied with thermodynamic theory and ionization energy principles.The two rules obtained have both inner relations and differences in objective conditions.

Key words: ionization energy,standard enthalpy change,standard entropy change,standard free energy change,standrd electrode potential
